Anyhow, I see where you are coming from. But then you aren't talking about thought experiments "per se" anymore (this dude even lowkey criticizes Gettier somehow!) but just warning not to talk out of one's ass like in any other kind of argument.

Like, those atrocious "should the car kill the elderly or the baby" are either more of an engineering problem than truly philosophy, or they are ethics from somebody that thinks either too sanctimoniously about people or too stupidly about computers.
