> they'll realize that's no longer possible

It definitely is. AI isn't perfect yet. It still has well-known flaws like the inability to count letters or say "I don't know". Definitely harder in the form of an essay than a conversation though. Especially because there's a decent chance someone has written "the answer" on the web somewhere and AI can just regurgitate it.

These are flaws from 6-12 months ago. You might want to spend some time talking to Opus 4.7 or GPT 5.5. I can assure you that they can count letters just fine.

You’re right that AI isn't perfect, but it’s pretty good. Especially since December last year which was an inflection point in capability.

		Those don't seem to be available for free so I'll take your word for it on the letter counting. They still can't say "I don't know" though can they? I think it would still be pretty easy to weed out AI in a Turing test with a competent examiner and a human that wants to prove they are human.
