I just realized, why don't they have some "definitely human" third party cookie that caches your humanness for 24h or so? I'm sure there's a reason, I've heard third party cookies were less respected now, but can someone chime in on why this doesn't work and save a ton of compute?

Because people will solve the challenge once, and then use the cookie in automation tools. It already happens with shorter expiration cookies.
