Back in early 2023, the state of google search was abysmal (despite that their leaders insisted it wasn't, it had become nearly unusable for me and I don't think was that unfounded of an opinion). Microsoft rolled out a new version of bing, which became bing chat - search worked for me again for a very brief window of time.
They could have pounced on this opportunity to take a big chunk out of google's search, because google didn't really catch up there til the AI overview was rolled out, and even that is notorious for having issues. Eventually chatGPT seems to have carved out some of this search space with web-search being native to the tools now.
But microsoft was way ahead of everyone here for a brief period! Instead they just rolled everything into bloatware vaguely called "Copilot" and called it a day.
this is an extremely unfounded opinion, and pointing me to other people on hackernews that agree with you is not evidence. Google search quite literally was and continues to be the most successful and profitable product in the history of humanity. None of your comment interfaces with reality at all.
