Okay, so it isn't just me.
I was watching a show about channel boats and the guy was talking about keeping the landline current isolated from the boat so his aluminum* hull wouldn't get damaged. I wanted to make sure I understood that principle (both HS and college Chemistry were a while ago), and also confirm that it was the same reason you don't want to mix copper and steel plumping.
*I guess aluminium, since it would be a British boat.
So I google it (rather proud that I remembered the term) and the google suggested a YouTube video with an AI 'babe' in a bikini or lingerie and lab coat as thumbnail. This is a little concerning because 1) we don't watch 'adult' material through our internet, 2) could very well have kids doing this googling, and 3) the subject was base chemistry concepts. So we watch it (out of morbid curiosity), and other than a rather ASMR-ish AI female voice, it's a normal chemistry explainer video. So Google or the YouTube algorithm thinks we need glorified booth babes (as in there just for the thumbnail) for completely untawdry google topics.
I did the same search at work (just the search) and it comes up with a different AI-generated-thumbnail video, this time with cleavage-ful woman in construction hat & vest. So it even knows to toe the line for places of business. I just... future generations are going to have a really weird opinion of us and I want to yell down the ages "I did not agree to this!"
