You’re 100% right. I just grasped at the first example I could think of where the crawlers could do free work. Yours is much better. Left is best.

I went back and added “malicious” because I knew it wasn’t useful in reality. I just wanted to express the AI crawlers doing free work. But you’re right, bitcoin sucks.

Can there be a challenge that actually does some maliciously useful compute? Like make their crawlers mine bitcoin or something.
