Long before GenAI, I saw people using meme generators a lot in corporate presentations. I found that equally jarring. Replacing that with GenAI stuff is probably an improvement. At least it's reducing legal risk. It seems more understandable to a global audience, too.
I still don't have an explanation why people are doing this. Is it part of leadership training? Or do presenters have their own theory that including this stuff makes the presentation more memorable and enjoyable?
People have a thing that they mimic the behavior of those above them in the hierarchy. CEO used a meme once because they thought it's funny, then everyone did this in order to mimic CEO.
Why was leetcode so popular? Because Google did it and they were the cool kids at the time.
