Short rant, but there's something awful about being blocked after authenticating by a puzzle - not one of those smart CAPTCHAs - that requires you to prove you're human just to log in to one of the most powerful general purpose AI services in existence today.
People don't complain enough about these tests, but I expect them to come to the fore as AI becomes more of a thing and users begin to feel like they're being treated as second-class netizens just because they're human.
