The deterioration of Google
The “algorithm” seems to have become a black box even Google engineers can’t figure out
The fact that over a year ago ML experts at Google (El-Mahdi El-Mhamdi at least, if I recall correctly) who have since left warned that LLMs should be avoided because they made products chaotic and hard to control seems relevant.
As is the fact that around the same time others also warned that one common consequence of mass layoffs is they tend to turn internal systems into black boxes because everybody with a deep understanding of them has left.
