I see it in the USA.

I quit Google search and I wouldn't normally type a search on the google.com homepage anyway.

Uh, the search button is still there on their homepage? Maybe it's a test in specific countries?

Pesquisa Google = Google search

Hmm... if only there's literally any other search providers in existence...

I haven't touched google in years. They won't be missed.

Source it’s being removed?

That would completely defeat the purpose of Google

I hadn’t noticed.

Looks like it only applies to Android phones and only the Google app search page (who uses that?) and though it looks like an AI button it (also?) returns search results.
