I think this is a non-issue

Captchas aren't easy to bypass - run of the mill scammers can't afford a bunch of servers running cutting edge LLMs for this

Captchas were never a guarantee - one person could sit there solving captchas for a good chunk of a bot farm anyways

So where does that leave us? Sophisticated actors could afford manually doing captchas and may even just be using a call-center setup to do astroturfing. My bigger concern here is the higher speed LLMs can operate at, not bypassing the captcha

Your run of the mill programmer can't bypass them, it requires actual skill and a time investment to build a system to do this. Captchas could be defeated programically before and still can now - it still raises the difficulty to the point most who could bother would rather work on something more worthwhile

IMO, the fact this keeps getting boosted makes me think this is softening us up to accept less control over our own hardware
