Re: True AI - nobody sees it for what it is
That's why I use merchant-locked, charge-restricted virtual credit cards, except for the rare site where they're disallowed by the provider (privacy.com) or not accepted by the merchant (in which case I'll usually forego the purchase, because why bother with incompetence?).
And, no, I don't let the browser remember them. For one thing, there's a different "card" for every merchant.
Before that, I always entered my details manually. This Nate service sounds like the ultimate Lazy Rich People's product (aside from disabled users, for whom I'd think browser auto-fill would probably be nearly as good). Honestly, online shopping is already a tiny fraction of the work that real-world shopping is.
