Very cool. I do have a couple of questions tho:
1. You mention "Unaffected by AI intelligence" - how does that work?
2. How does it identify and block bots?

1. At it's core, it's a Proof-of-Work captcha, so compute load depends on the usage pattern. AI (LLMs) does get better at image/audio recognition, but compute task is the same anywhere, does not matter who "clicks" the checkbox.
2. Bots usually have such access patterns that cause compute task difficulty to become prohibitively high, requiring exponentially more CPU resources. This renders bots economically nonviable for submitting forms or scraping website.

I've heard doing nothing can cause a significant physical discomfort to the impatient mind.

very cool touch, i was personally not patient enough, but likely my users won't be too, so this seem like a useful product

Yeah, most people here probably have an overstimulated mind and just doing the opposite for a minute or so can be very tough at first!
