There are new ideas, people are finding new ways to build vision models, which then are applied to language models and vice versa (like diffusion).
The original idea of connectionism is that neural networks can represent any function, which is the fundamental mathematical fact. So we should be optimistic, neural nets will be able to do anything. Which neural nets? So far people have stumbled on a few productive architectures, but it appears to be more alchemy than science. There is no reason why we should think there won't be both new ideas and new data. Biology did it, humans will do it too.
> we’re engaged in a decentralized globalized exercise of Science, where findings are shared openly
Maybe the findings are shared, if they make the Company look good. But the methods are not anymore
