    @SebJohnsonUKOne of DeepMind's most senior researchers has just left to redesign AI from the ground up. He was part of the team that developed AlphaGo and beat grandmaster Lee Sedol. Now he has left to build his own AI systems, on the belief that current LLMs are unable to "reason". He told @FPratty that: "we need to go back to the architecture and fundamentally redesign it so that it does proper reasoning,” VERY INTERESTING He hasn't raised a mega round like lots of other ex-deepmind researchers, and he is unsure on whether he will or not. Either way he is ONE TO WATCH. @ThoreG
