Strong plus one here. Not only that, but it uses gobs of energy in total. Google has reneged on all of its carbon promises to stay in the running for AI domination and to head off disruption to search ads business. Since I've unconsciously trained my brain to not look at the top search results anymore because they long ago turned into impossible-to-distinguish ads, I've quickly learned to just ignore the stupid AI summary. So it's an absurd waste of computational power to generate something wrong that I don't even want to see, and I can't even tell them to stop when they're wasting their own money to do so.
It’s often wrong anyway. Much like you, the thing that annoys me most about it though is all the power they must be using having it run on every single search by anyone.
