📅 Jul 18, 2026 Sourcery with Molly O'Shea 41 MIN 5467 VIEWS 191 SEGMENTS · 11 SPEAKERS
Day 1 of RAISE Summit in Paris, the most high-profile AI summit in Europe. We pulled 10 of the sharpest founders, operators, and investors aside for their hottest takes on the debates defining AI right now. Open source vs closed models dominated the room, alongside agents rewriting how work gets done, the death of the keyboard and mouse, the economics of inference, and physical AI moving from data centers into cars, devices, and even orbit. Real numbers, real disagreements, and a few pieces of breaking news, straight from the people building it. "The keyboard and mouse are slowly dying." - M...

What Philip Johnston said

Written from the verified transcript and checked against it. Every figure links to the moment it was said.

Philip Johnston, CEO of Starcloud, said the SpaceX IPO will be viewed historically as the most undervalued IPO of all time, predicting SpaceX will tear through $10 trillion in valuation within the next couple of years and have almost unlimited total addressable market. He is bullish because SpaceX owns the most cost-effective launch vehicle, which opens up every space industry, comparing it to owning the railroads. Johnston said Starcloud is chip agnostic, having flown three ARM GPUs on its first spacecraft, and hopes to fly SambaNova and Cerebras chips. He announced Starcloud is moving into a much larger facility in August to build a manufacturing line for StarCloud 3, a vehicle that fits on Starship and can carry up to 10 megawatts of compute capacity per launch. He was surprised SpaceX quoted his article on data centers in space in their S-1 filing.

  1. 23:18We have Philip Johnston of StarCloud, one of the hottest companies in space right now. Philip, how's it going?
  2. 23:28How does it feel to be in SpaceX's S-1?
  3. 23:58Okay, so we have to ask you, we're here on Earth, but what is your hottest take right now?
  4. 24:28This is not investment advice, but why are you so bullish?
  5. 25:14Do you have a favorite chip?
  6. 25:49Are you guys outgrowing it already? What's going on?
  7. 26:22So, as we close out, what are you most excited for for this week?
Molly O'Shea 0:00 ↗
Raise. Raise. Paris. Paris is beautiful, but it's hot as... Paris, in the middle of the summer, middle of the heat. People are ignoring it. They're showing up.
Okay, we have a very special guest. I know I've said that before, but we really do this time. Coming off the heels of the Jamon interview at CO2, we have Max Cook of COTU. Max, welcome.
Max Cook 0:29 ↗
Thank you. Excited to be here. It's pretty nice.
Molly O'Shea 0:31 ↗
It is very nice in this very secret location in Europe, which we cannot talk about. Not... not disclose the official location, but you've got an old cement wall, which you have many of in Europe, so it might be anywhere.
Max Cook 0:43 ↗
It could be anywhere. It could be a country that Philippe and Thomas know very well.
Molly O'Shea 0:47 ↗
True. That is true. Cannot confirm though. No.
Okay. So, we have to get into this. I think you have a couple of big insights you want to share with us today.
Max Cook 0:57 ↗
I hope they're insights, but yeah, I mean, I have a couple things I've been thinking about.
Molly O'Shea 1:02 ↗
Like, what's your hottest take?
Max Cook 1:04 ↗
Hottest take might be that the keyboard and mouse are slowly dying. I think... damn... I think code too. You've heard Jamon speak about it. You've heard Philippe and Thomas speak about it. We talk about big tech waves. You went from mainframe to PCs to networking the PCs to desktop internet, which is where you get a mouse and keyboard, to mobile internet, which is where the iPhone supremacy began. And with each of these big waves, we end up interacting with compute, interacting with computers in a different way. And it seems pretty clear at this point. I think there's a good stat that like the average person has 60 to 80 apps on their phone.
Wow. They use 11 apps daily on average and 30 apps in any given month. Like it seems quite clear that we're going from a world in which you have 60 to 80 apps to an agentic AI world where you've got a lot fewer than that. Two, three, four apps where everything else plugs in as an API or an MCP. Um, and in that world, it would only make sense that we reinvent how we interact with compute. It's not the keyboard and the mouse. It's probably natural language. Like if we're talking, we speak in natural language. If you're working with a coworker, you ask them what to do, you figure it out together, and you go do it. So, I think there's been a number of good discussions about this. Uh, Mikuel from Replet was talking about how uh natural language is how people communicate. That's clearly the direction we're going in. There's a Greg Brockman quote that I always think about. I'll butcher it, but he had a tweet about we've always conformed ourselves to computers, like with D by inputting specific data with a keyboard and a mouse, and now we're finally entering the era where computers have to conform to us. And so this microphone is reminding me, we're already seeing it at CO2, like in the famous CO2 bullpen that you got to see. Uh, we've got a number of investors that are whispering into their collar half the day.
Molly O'Shea 3:02 ↗
Really?
Max Cook 3:03 ↗
Because that's how to give models better context, better prompting, and ultimately like produces much better work output. So that's my take. The keyboard and mouse, you should throw them away, and we're going to natural language interacting with agentic models.
Molly O'Shea 3:17 ↗
Sounds like bullish on humans.
Max Cook 3:19 ↗
It's bullish humans. Yeah. No, I agree. Yeah. I think sure we're building for like an autonomous agentic future, but also there's going to be a lot of that which is just supercharging humans. Like that's what we see at K2 is all of our analysts, all the investors that are whispering into their collar are producing better and more work output because they're able to more fluidly interact with these models. Like I think the Thinking Machines interaction model demo that came out in May kind of went uh underloved. Uh, there wasn't enough hype around that.
Molly O'Shea 3:53 ↗
Really? Why? Say more.
Max Cook 3:55 ↗
Yeah, I mean, to me that Thinking Machines interaction model demo was like a bit of a peek into the future. You're going to interact with compute at all times. It's got to have zero low latency back and forth. It has to be able to input images, understand what you're saying in real time, respond to you. And so I watched that and said, of course, this is like going to sit on top of every intelligence layer, every model, every app. That's how we're going to interact with compute. And I think people were excited about it at the time but haven't necessarily put the dots together between speech-to-text interaction models and thinking about the historical context, which is that every single time we've moved from one era of tech to another, the device has changed and how we interact with that device and with compute has changed. So I think it's only logical that that's happening again now.
Molly O'Shea 4:43 ↗
Damn. Also sounds like you need Assembly AI speech models.
Max Cook 4:48 ↗
Definitely, yeah. I know Assembly is working on it. There's a lot of exciting companies that are working in this space and I think we'll see what the device ends up looking like. But I think there will be a new format, a new way to interact with AI versus how we used to input data into a structured output via graphical user interfaces, GUIs, apps, keyboards, mice. Like to me, we're going to look back in five years and say, of course, we're not using keyboards and mice anymore. Like we've come up with a better way to interact with intelligence.
Molly O'Shea 5:20 ↗
All right, so we'll upgrade your wires to Neuralink chips.
Max Cook 5:25 ↗
Yeah, maybe that's it. I mean, obviously wearables is a place people are spending a lot of time. Neuralink is a place people are spending time. I don't know what the answer is, but like to me, it's a hell of a lot easier to see that like the keyboard and mouse are dying a slow death. I can't tell you. It's for smarter people than me, builders, operators, founders to figure out what the new format looks like. But I think that has to be the direction we're going where you've got OpenAI coming out with a super app for the first time that's going to introduce their almost a billion weekly active users to agents for the first time. It's going to change how people interact with their phone and change how people want to interact with their phone. And we're going to need something new for that.
Molly O'Shea 6:04 ↗
And probably some MongoDB databases for all those apps.
Max Cook 6:07 ↗
Yeah, definitely. I mean, you've seen it. You've seen it in some of the public software companies already and in private too. Snowflake, Databricks, uh, Datadog, all of these businesses that are tied to growth in AI app production, AI app development are doing great and it's going to be the exact same type of story.
Molly O'Shea 6:26 ↗
Amazing. Well, Max...
Max Cook 6:28 ↗
I have one more.
Molly O'Shea 6:30 ↗
You have one. Just wait. There's more. What is the second hot take?
Max Cook 6:34 ↗
One more just because I've been spending a lot of time on it. Um, this one I don't have an answer for. So I'll just leave you with a question that I don't think people have thought enough about.
Molly O'Shea 6:44 ↗
Okay.
Max Cook 6:44 ↗
There's a lot of discussion of open source models versus closed, the frontier, OpenAI and Anthropic right now. Um, a lot of the discussion I see is sort of there's either one is a winner and one is a loser or the other is a winner and the other is a loser. I think that's totally the wrong way to think about this. I also think like there's been some great posts. Jesse Zhang from Decagon posted recently on X about how, I don't want to get his numbers wrong, but I think 90% of Decagon's workloads run on open source models.
Molly O'Shea 7:14 ↗
Damn.
Max Cook 7:15 ↗
And that is because they are at kind of production scale. They need low latency. They need to be able to fine-tune a model and use a small model for that low latency. That's not a product that Anthropic or OpenAI are offering today. You can't do that with whatever their frontier model is. Um, so they're on 90% open source, yet at the same time enterprise LLM spend was 19% open source last year and it's 11% this year.
Molly O'Shea 7:44 ↗
So it's dropped.
Max Cook 7:46 ↗
Yet you've got businesses like Decagon telling you that 90% of their workloads are done via open source. Jesse's explanation I think is the correct one, which is that open source is good for production-grade, like production-scale workflows, yet we're so early in this AI journey that there's not that many production-grade workflows. And so if you are trying to discover a new use case, you want the smartest model you can possibly get, you use the frontier. Um, and I think the question that I don't think is being asked in this open source closed frontier debate is: Clearly, people want to do model routing. People clearly want to fine-tune and customize smaller models. I don't think anyone's asking the question of what happens when Anthropic and OpenAI decide we can offer that as a product. I don't know that they're going to do that, but it seems plausible that they would see this opportunity to take their older, cheaper, more efficient, smaller models and sell that as a product. I wonder if OpenAI will open source.
Yeah, I don't know. I mean, as of now, they won't, but model routing, I think, will be in their best interest. Maybe fine-tuning of some kind. Uh, so that's like the question I don't think is being asked enough when we consider what does the end-state compute ecosystem look like, X% open, X% closed. I don't think people are thinking about the idea that like a Microsoft who's saying they can help you build your own model and fine-tune that, that Anthropic and OpenAI could just as feasibly offer that product at some point.
Molly O'Shea 9:22 ↗
Damn. Well, we just had Matan from Factory on and he said within his enterprise customers he saw in the beginning of the year it was less than 1%, got to 1% in January, then I think it was this month or something like that. I could be quoting this completely wrong, but it got to 10% open source.
Max Cook 9:40 ↗
Open source. Yeah. I mean, you're seeing it on X, which is obviously one of the better places to see some of the people on the forefront talking about what they're doing. I don't think that's a crazy end state of the world. End state of AI compute, AI inference would be, I don't know, 10% open source. Like the Decagon, Jesse's article made a ton of sense. If you know all of the parameters of the workflow you're trying to execute, you've thought about all the edge cases, you've used a frontier model to hone that, then it makes sense that maybe you're actually seeing better capability with an open source model that's fine-tuned, or the combination of a frontier model for your hardest tasks and an open source or previous version of a model for your kind of production-grade workflows. Like customer service is a great example of that. But to me, we're really just so early on in terms of what will be the kind of adopted production-grade workflows that are built on top of these AI models that the frontier is... I mean, everything's growing. And so I think that this kind of zero-sum discussion of open versus closed is missing the point and there are a lot of questions that I don't think people are fully thinking about yet. But it's interesting. Like, it's fun to be sitting in a world that we don't know what the end state looks like, but it's our job to at least try to predict what it could be.
Molly O'Shea 11:04 ↗
Amazing. Two hot takes. And I think where we are, which is not a very large palace in a very random European country, is a good symbolism of how far AI has gone. We can now buy palaces.
Max Cook 11:23 ↗
True. True. Yeah. I mean this is just the early days of AI.
Molly O'Shea 11:26 ↗
This is just the early days. This is literally just the early days where we are. So...
Max Cook 11:30 ↗
So room to go.
Molly O'Shea 11:32 ↗
Speaking to that and Rays, what are you most excited about with Rays this year?
Max Cook 11:38 ↗
Yeah, I mean I think the lineup of speakers is amazing. That cuts across like the compute layer, infrastructure layer, app layer. There's investors, there's venture investors, uh, public equities investors. And so to me, to have all these people in one place to be able to talk about these questions that I'm asking around open source, frontier models, uh, sovereign AI, um, the power constraints, grid bottlenecks. Like, that's what I focus on all day every day with my colleagues at CO2, but it's really, really damn fun to get to talk about it with founders, operators, entrepreneurs and hear what they're thinking on these same topics. So having all these people in the same place is what I'm most excited for.
Molly O'Shea 12:16 ↗
Amazing. Great place to end it. Thank you so much, Max.
Max Cook 12:19 ↗
Yeah, thanks, Molly.
Molly O'Shea 12:21 ↗
The sun came out for Henry. Henry, thank you so much for having us here in this very secret location. And I think we're in Germany. Is that correct?
Henri Delahaye 12:28 ↗
Exactly. We are in south of Germany. Thanks for being here, Molly. It's going to be a fun night. Thanks for being here. And uh, welcome.
Molly O'Shea 12:35 ↗
So, tell us about Rays this year. It's huge and very fancy.
Henri Delahaye 12:38 ↗
Yeah, it's fun. Like the idea was to bring the German subculture. So, we're not in Germany. We're in France. We can't really disclose where we are. That's part of the night and the whole deal. But uh, no, it's kind of bringing like a very different iconic experience to a very tech event. So we are all in our tech bubble, uh, token maxing on a daily basis, but it's good to have a bit of a history on our side, right? So thanks for being here.
Molly O'Shea 13:04 ↗
Of course. I know you're the most popular girl at the party right now. So we're going to keep this really, really short. What is your hottest take right now?
Henri Delahaye 13:10 ↗
So my hottest take is Germany is actually extremely beautiful and we're super extremely fortunate to be here.
Molly O'Shea 13:17 ↗
Perfect. Thank you, Henri.
Henri Delahaye 13:19 ↗
Thank you, Molly. Have a good night.
Molly O'Shea 13:21 ↗
You too. We're here with Pim of General Intuition. Pim, welcome to Sorcery.
Pim de Witte 13:25 ↗
Thank you for having me.
Molly O'Shea 13:26 ↗
Okay, so for those who don't know what General Intuition is, can you give us a little brief overview?
Pim de Witte 13:30 ↗
As humans, uh, we can talk or choose to sort of output text as one of the actions we can take, whereas an LLM is kind of the only thing they can do. So we train models that can predict lots of different actions where text is just a subset, um, which is a much more general approach than LLMs.
Molly O'Shea 13:47 ↗
And what is your hottest take today?
Pim de Witte 13:49 ↗
Uh, most of AI is just glorified data science.
Molly O'Shea 13:53 ↗
Damn. Say more.
Pim de Witte 13:55 ↗
Uh, good models mostly are downstream from good data and simple things.
Molly O'Shea 14:01 ↗
So what are you most bullish on in that respect?
Pim de Witte 14:04 ↗
Uh, really good data sets for the most part.
Molly O'Shea 14:08 ↗
Where do you store that data?
Pim de Witte 14:09 ↗
Uh, I cannot disclose that.
Molly O'Shea 14:12 ↗
Well, if you need to store your data, put it in MongoDB databases.
Pim de Witte 14:16 ↗
No, no, no, no.
Molly O'Shea 14:19 ↗
Okay. All right. Any other hot takes?
Pim de Witte 14:22 ↗
Yeah. Uh, Yan Lun is underrated.
Molly O'Shea 14:24 ↗
You think Yan Lun is underrated? Why?
Pim de Witte 14:27 ↗
Uh, the French just told me to say that. It's like I pulled into a room and they were like, 'You have to say this. I'm saying this.' Seriously, no more comments.
Molly O'Shea 14:35 ↗
No more comments. He's got to walk away now. Out of here. I may not. Damn. Okay. She have him. Oh my god.
Hi. Okay. We're here with Mark, CTO of AMD. Mark, welcome to Sorcery.
Mark Papermaster 14:51 ↗
Thank you, Molly. Glad to be here.
Molly O'Shea 14:52 ↗
Amazing. We're in a very secret location in a European location. We can't... you don't know where we are, but it's very secret. Okay. So I have to ask you, we're at the Rays Summit. AI is booming. What is your hottest take right now?
Mark Papermaster 15:07 ↗
Hottest take is people don't even understand how transformational agentic AI is. It's just transforming how work gets done. You know, just entire end-to-end workflows are being reimagined and I think it's starting to come out when you hear some of the stories this week at Rays.
Molly O'Shea 15:22 ↗
And what is your biggest lesson that you learned in the last maybe two or three years of this boom at AMD?
Mark Papermaster 15:29 ↗
Well, AMD, we got ahead of it. We've worked getting our CPUs and GPUs ready for this. And now with these agentic workflows, you actually need both. In fact, the ratio of CPU to GPU is becoming like one to one. Um, but none of us anticipated how fast these agentic workflows would just take off. Last six months have just been amazing and it's just a harbinger of what's yet to come. We're just at the early stages.
Molly O'Shea 15:54 ↗
How many agents are you using today?
Mark Papermaster 15:56 ↗
Every day I start with agents. They run my day, look at what's coming up. But what's really cool is how we do our chip design. We have thousands of sub-agents just doing incredibly complex chip design, speeding how fast we can get the next generation to market.
Molly O'Shea 16:13 ↗
Amazing. Okay, as the drums roll, what are you most excited about with Rays this year?
Mark Papermaster 16:20 ↗
Rays. Uh, well, it starts with the president of France and it ends with Yan Lun. I think we're going to... we got it bounded pretty well here. No, it's great. It's really great speakers. I think we're going to really hear some insights across every facet of the AI ecosystem.
Molly O'Shea 16:34 ↗
Amazing. Well, thank you so much, Mark. Really appreciate it.
Mark Papermaster 16:37 ↗
Thank you, Molly.
Molly O'Shea 16:38 ↗
Okay, we're here with Robin of Black Forest Labs again at a secret location in Europe. Robin, welcome to Sorcery.
Robin Rombach 16:45 ↗
Thank you. Hi. Nice to meet you.
Molly O'Shea 16:48 ↗
Nice to see you. I saw you a couple months ago.
Robin Rombach 16:51 ↗
Really? Where?
Molly O'Shea 16:52 ↗
In London at the Legends Gala.
Robin Rombach 16:54 ↗
That's right. Yeah. Yeah.
Molly O'Shea 16:56 ↗
Tough night. Anyways, okay. So, for people who don't know, what is Black Forest Labs?
Robin Rombach 17:04 ↗
Uh, we are building multimodal visual models uh for content creation and for um now physical AI.
Molly O'Shea 17:13 ↗
Amazing. And so we were talking about a couple hot takes earlier, but I'm really curious. What is your take on open versus closed, open source versus closed?
Robin Rombach 17:27 ↗
I mean, you can approach this from like so many different angles, but I think like the most important one is um that open innovation is good for the world. And I think fear-mongering around AI models is only going to lead to them being more closed and that's ultimately going to slow down all AI progress. And I think ultimately it's super important that uh AI is actually an accessible technology. It's also going to make it more um safe in the end. I think that's like something that is a pretty fundamental principle. If you then think about like business models that you build around open versus closed and all of that, then you can like start to be like more elaborate. But I think fundamentally open innovation is good for the world. Is it open weights? Is it open source? It doesn't really matter in the end, but I think having accessible AI models is key.
Molly O'Shea 18:16 ↗
So you're based in Black Forest, Germany. We're here in Europe and there's a nice convergence of European tech and American and Silicon Valley, everything that's converging over here. What should people know that aren't from Europe about what's actually going on in European tech right now?
Robin Rombach 18:40 ↗
Um, I think it's getting better. There's not enough going on yet, I would say. Um, even though I don't know, there's like a fancy event like this. Uh, like it looks really nice, right? But I think like what really matters in the end is that Europe is not known for having like, I don't know, nice castles or stuff like that, but actually nice AI or nice technology. And I think that's something that yes, it's changing and I think like events like that where a lot of people come here, I think that's a good start, but ultimately there needs to be like a fundamental mindset to really push AI innovation from here as well.
Molly O'Shea 19:13 ↗
I know you're super excited about the Rays Summit. So, what makes you so excited?
Robin Rombach 19:20 ↗
I'm not going to answer this question.
