I don't see AI summaries, nor advertisements on Google Search results, because I use uBlock Origin. I started using it to block (mal)vertising. When Google started pushing AI summaries, I added the filter to uBlock Origin to block those, too. When Google modified Chrome to gimp Add Ons like uBlock Origin, I switched from Chrome to Firefox, which doesn't impair it. What I see are the simple Google Search results, with none of the bloat.
