Google is clearly trying to push that AI Mode button right into the search bar on the results page now. It's getting harder to just run a regular follow-up search without hitting Enter because it feels like they're
removing the standard search button entirely for some users. I can't tell if this is a widespread rollout or just some weird A/B test since it doesn't show up for every query, but it's definitely annoying to deal with when you're trying to iterate quickly on Google Search.
