It's always this.
I remember some post from years ago by a person saying that Elon Musk seems like a genius up until he starts talking about something you're familiar with.
Thanks to the Internet, I think it's gotten both more difficult to hide your own stupidity unless you're careful with your tracks (the power-hungry often aren't) and easier to absolutely flood the discourse so that your inferior cognitive abilities are either lost or overshadowed by something else (like Trump doing everything he, unfortunately somewhat successfully, to keep people busy talking and thinking about so much more other than his ties with Epstein).
And it keeps showing with the political and corporate leaders. The smarter ones from the latter, unfortunately, mostly seem to be psychopaths and/or sociopaths, very keen on leading the former where they need them (currently supporting AI and preparing the bailout, curbing the competition before, probably staring jaw-dropped at the news of "AI going rogue" and how can be the end of humanity and all).
Imma beat the dead horse and say that out of all dystopias, Idiocracy (2006) turned out to be the most accurate.
