Sure. I mean, since the early stages of any work that I've done, back in 2008 that we can even call remotely digital, and especially in the context of a manufacturing environment and even in a smart building environment, the value of the network was so ubiquitous that people used to think that, hey, what is a data need? Of course it's available. All I need is to create pipes that will essentially transfer the data from the point it's getting generated to the point where I need it to be. And hence there was a huge rush of investment into cloud and into analytics, and this whole world of big data started. The need for data scientists exploded, the need for data engineers exploded, and people invested billions and billions of dollars in platforms with the simple assumption that with relative ease we can make data move, and as long as we could find the data to reach its targeted destination, some magic models will crunch it and we're going to create insights, and the world would be a far more productive place. Guess what? 15 years or more since then, it hasn't happened. And when people try to diagnose as to why is it so — our quality of analytics delivery has improved, the amount of computing power in cloud platforms has improved — why are models and change management struggling? You really go into the core and you realize that the assumption has always been that if a manufacturing process has a physical self in which things are working, our current networks, our current technology infrastructure was built to essentially imitate that physical world into a digital world in a cloud environment, but it was not true. Which means that, and I use this term — it's a little technical, but I think it's also self-intuitive — the physics of the manufacturing process, if you have to imitate it well in the digital world, the current technology infrastructure needs significant upgrading. And there is complexity. For example, we have historians, we have MES systems which often sit between the sensor and the cloud. One of the first things the MES does, of course for obvious the right reasons, it averages data. So a signal can get generated in a few milliseconds, if not less, but systems that are sitting in the middle average them, they smooth them, and when they transfer that data into a cloud platform, guess what has happened? The actual physics of the process has got lost. Now one might say that why can't analytics work on smoothed data? And this is where people have realized the reason it cannot be fully successful is because the insights that need you to manage the physics of the process lies actually in the jitters of the data that got smoothed. So it's just not important to know what was in general the average temperature of a cement kiln or a chemical plant or a boiler; it's important to know the fluctuations of that temperature around the average line which creates insights. The moment this was realized, that we now need to create infrastructure that will essentially reflect the true physics of the manufacturing process in a computing platform, two things happened. One, network became the most important technology infrastructure for success of digital transformation. You need a pipe that will transfer high-frequency sensing data directly, safely, securely, and in an accurate manner. You cannot have a pipe that either cannot give you safety of IT and OT integration; you cannot have a pipe that averages physics; you cannot have a pipe that is not reliable, because the analytics platform needs reliability, it needs security, it needs clean data. It became important. And as IoT proliferated, it also became obvious that you need bigger and bigger pipes. And the concept of cloud computing became non-sustainable because bigger pipes mean more money, it means more technology infrastructure cost. So now networks have become the only solution to provide clean, secure, and harmonized data. It has also become the only logical destination for edge computing because you cannot take all data at the highest frequency reliably to a remote cloud. So these two confluence, this understanding that the role of the networks to provide data of this targeted quality and consistency and security, and the fact that we need to operate at the edge, has completely blown the lid of how people have started perceiving networks. And it's now concluded that you cannot have a digital twin successfully running in multiple sites of an industrial platform or multiple buildings in a smart infrastructure unless you think through the networking infrastructure that binds it.
