Most of those things weren't very good before AI was applied.
Translation specifically was pretty bad before Google applied machine learning methods to it around 2007 when it became very good almost overnight.
Google Translate isn't what's meant when tech CEOs say "AI" in 2025.
Stop blurring the lines, google translate using machine learning has nothing to do with turning firefox into an ai browser
Google Translation never "became very good" and it still isn't when you compare it to DeepL or Kagi.
Where it excels is quantity. Often, niche languages are only available on Google Translate.
