It's even worse than that. Most people have no idea how far CGI has come, and how easily it is wielded even by a couple of dedicated teens on their home computer, let alone people with a vested interest in faking something for some financial reason. People think they know what a "special effect" looks like, and for the most part, people are wrong. They know what CGI being used to create something obviously impossible, like a dinosaur stomping through a city, looks like. They have no idea how easy a lot of stuff is to fake already. AI just adds to what is already there. Heck, to some extent it has caused scammers to overreach, with things like obviously fake Elon Musk videos on YouTube generated from (pure) AI and text-to-speech... when with just a little bit more learning, practice, and amounts of equipment completely reasonable for one person to obtain, they could have done a much better fake of Elon Musk using special effects techniques rather than shoveling text into an AI. The fact that "shoveling text into an AI" may in another few years itself generate immaculate videos is more a bonus than a fundamental change of capability.

Even what's free & open source in the special effects community is astonishing lately.
