Yeah, this has been a tough one. I think I would say right now punching below their potential, but I think it's going to change and I'll explain why. First, when we talk about cell therapies, of course the focus after our initial discoveries and then other companies Kite, Juno, then later BMS and Gilead, Bluebird also was in there successfully bringing forward cell therapies were primarily focused on B cell cancers, right? And I think very successful, but the business was not hugely successful mostly because complexity, cost of goods, profitability challenges. Now I think what's really interesting is, and we could have never predicted it, but because of the work of Georg Schett in Erlangen, Germany, we've suddenly learned that you can actually use these therapies to reset the immune system. And I think this is going to be a huge opportunity. Just remarkable. And when you look at this data sets, as you know, very rare that you see data like this. Very rare that you can rewind a disease or completely in some cases almost create a functional cure for patients with end-stage immunological disease. These are the autoimmune diseases that have been very life-impacting chronic conditions, chronic debilitating with very bad options. I mean, the story I like to tell is one of our sentinel patients was an individual in bed all the time, not able to walk his children to school. He receives our cell therapy, strong results, two months, six months later no sign of disease. He has gone from almost a near-death situation to normal life. I mean, this is extraordinary, this is like Lazarus-like things. So we've now taken that forward into four pivotal studies. We have, I think, six more programs in early stage clinical, other companies as well. And I think cell therapies and immunology is going to be a huge, huge area alongside immune reset, bispecifics, trispecifics. That is going to be a whole renaissance for cell therapy. And alongside that, what also happened is we figured out how to make the manufacturing factors less costly. I think that's the other part of that story. If we were just doing immunology but with the same cost structure, super expensive bespoke manufacturing, but now that we're all working on rapid platforms that take two days in the factory, 8 days vein-to-vein time, this is changing the game. So I think there now, as has often happened, there was the hype, then we went through the valley, and now we're coming back out the other end. I'm not sure any of us would have predicted that would have been in immunology and not cancer, but hey, so be it. I think gene therapies is a tough one at the moment, as you know, with the safety. Zolgensma has been hugely successful. We think a remarkable drug, amazing. The story for your listeners: this is for a terrible pediatric disease called spinal muscular atrophy. These children would face a certain death at two years of age, or if they have a less severe form, they live a life in wheelchairs and really debilitated. And Zolgensma, one-time gene therapy, if given early enough, can almost let children lead a normal life. So it's been a success story. Now, we had hoped we would have a whole series of those behind it, and as you know, it's one success story but it's an end of one story. This is not platformized yet. I think because a combination of factors: one, the trafficking of these gene therapies to the right cell type, getting the expression as you hope, safety profile, all of these things turned out to be much more of a puzzle, and there wasn't as plug-and-play as I think we initially expected. That said, I still think that for certain diseases, if you could get a one-time therapy, it would be hugely beneficial, particularly in children. And I still think there's more to do, there are more opportunities here. We acquired some companies around this, so let's see. But that one is still to be proven, whereas I think cell therapy is really maturing now.
