1. With too much protection, humans might be inconvenienced at least as much as bots?

2. Even pre current LLMs, paying (or otherwise incentivizing) humans to solve CAPTCHAs on behalf of someone else (now like an AI?) was a thing.

3. It depends on the value of the resource trying to be accessed - regardless of whether generating the captchas costs $0 - i.e. if the resource being accessed by AI is "worth" $1, then paying an AI $0.95 to access it would still be worth it. (Made up numbers, my point being whether A is greater than B.)

4. However, maybe solutions like cloudflare can solve (much?) of this, except for incentivizing humans to solve a captcha posed to an AI.
