I recall Stanford's past AI Reports being substantial and critical some years ago. This seems like a compilation of many small press releases into one large press release ("Key take away: AI continues to get bigger, better and faster"). The problem is that AI went from universities to companies and the publications of the various companies themselves then went from research papers to press releases/white papers (I remember OpenAI's supposed technical specification of GPT-something as a watershed, in that actually involved no useful information but just touted statistics who context the reader didn't know).
