No. But you can easily make and post content that is not easily detectable as generated.

You only notice plastic surgery when it's bad, but that doesn't mean all plastic surgery looks bad...

Who's "people"? The bottom X% (40%?) of the population is already falling for AI slop video scams, but before that, they were also falling for pig butchering and nigerian prince scams, so the "average" person benchmark has already been passed for text, photos, videos, etc. For more astute consumers, video isn't there yet.

There's also the question of whether people are even trying to disguise AI content, and how effective that disguise is. Are you or I missing the AI-generated text that just has a veneer of disguise on it?
