> A hacker news rumor was that they are paying $5M-$20M per year to the top neural net experts probably to make some exotic architectures to surpass transformer
This reminds me a TV interview of the author Patrick Modiano, just after he won the literature Nobel price. The presenter asked him if the money would help. The author answered essentially that the next time he would be in front of a white page, the money surely wouldn't help.
In the case of surpassing transformers, money could help to give access to more compute power. It could also help to prevent the research from being public.
