Should we start building sign-up flows for AI agents instead of humans?

I was thinking about how annoying traditional sign-up forms are with all the CAPTCHAs and email verification steps. If an AI assistant is trying to set up a service for its owner our current onboarding flows completely block it. Allowing bots to auto-create accounts sounds like a fraud nightmare but forcing a human to manually type in details feels outdated.

I'm leaning toward letting the AI fill out all the fields while keeping just one single click for the human to approve everything.

How are you handling this in your own apps are you keeping sign-ups strictly human, or opening the door for agents?
