I agree with this. Last decade was golden age of AI where all major players including Google brain, deepmind, FAIR, Microsoft Research contributed a lot. To honest OpenAI had the least intellectual contribution of them all except of few marketing material masquerading as papers. From now on we can expect all labs to secretive and not publish anything. This is really bad considering all this models are black box and research is needed to understand them better. Hope government comes into picture and forces this labs to explain details of each model
FAIR will continue to publish. Nvidia and Uber also. Then you have open source oriented labs who should continue publishing. Google is the big one. They have made more research contributions than all other labs combined basically.
