The part I hate the most is they got rid of the dictionary/thesaurus/etymology thing and replaced it with AI overview. Now "define <word>" or "<word> synonyms" gives you an AI overview with consistently worse output than the nice, consistent and deterministic dictionary output.
Yes, I hate this. The old knowledge panel was way better.
I've switched completely to Wiktionary for the dictionary and etymology part of that. It's obviously not perfect, but neither was Google for that matter. For the thesaurus part, whatever the first result on DuckDuckGo is is usually enough to knock some sense into my brain so I actually remember the word I want.
