Pretty weird but everyone seems chill about it
That’s not what they actually do. They simply introduce a barrier that’s cheap for a human to complete but expensive for a computer to beat. A captcha is about $1 per million to serve and to complete one is about $1.1 per million.

This is the reason and logic. There are no advanced algorithms deciding your “humanness.”
I’ve received captcha challenges that I couldn’t solve even if you gave me a million euros.
Reverse Turing test
It’s still written by a human. No different than a tool that measures our heart rate or checks our eyesight.
It’s pretty different.
Heart rate and vision have objectively correct ways to measure them. Bot detection doesn’t.
An algorithm is a tool made by us. OP suggests it’s something sentient.

I guess, yeah I hadn't thought about it in exactly those terms.
Is this like a reverse Turing test?

CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”, so yeah.
