Does HN ever require CAPTCHAs? It seems to do pretty well with its basic but battle-tested moderation/antispam tools, and rate-limiting that seems to repel all but the most concerted DDoS attacks. I don't think HN has any unreasonable restrictions on scraping or third-party clients, either. And it manages to serve 5M unique visitors a month and 10M views a day[0].

Earlier quoted context omitted.

I still find it funny that Google, with the advantage of having millions of Internet users train their AI like galley slaves for free, hasn’t yet been able to crack vision driven self driving. Tesla had no such advantage when training their FSD to recognize traffic lights, bicycles, motorcycles, etc.

Tesla, the company that just recalled 2 million self driving cars? In fairness, the company best positioned to harness user input to an AI that avoids crashes would probably be Rockstar. OTOH, that AI would definitely not obey stop signs or pedestrians.

A dystopian future we can all agree is more plausible than it should be

A neural implant that only kills 10% of monkeys.

Monkeys at the wheel is probably the solution for self driving cars.

Seems like we already have those amongst the Tesla FSD proselytizers.

Earlier quoted context omitted.

Tesla recalled two million vehicles after federal officials said it had not done enough to make sure that drivers remained attentive when using the system. Not because their self-driving system sucks, or whatever you were trying to imply.

If the self driving system were worth it's salt, it wouldn't matter if the drivers weren't paying attention. Ergo, the system sucks, or is at the very least not nearly as good as Tesla likes to tout.

Well it's not like there's a self driving car system in operation today that does not require a human in the driver seat at all. Waymo has so much catching up to do.

Google CAPTCHAs were designed and deployed as a mechanism to train AIs. That's why they are the way they are. Any security theater surrounding them is entirely incidental. So it's no surprise that the AIs are now good at solving them. We've trained them for years.

All true, except: While these are considered just an excruciating security pain for users, they do serve a non-theatrical purpose in many cases of throttling the speed of brute force attacks (or at least costing your opponent money).

> they do serve a non-theatrical purpose in many cases of throttling the speed of brute force attacks

Might do that unobtrusively for the average person, by using projects like mCaptcha [0] for instance.
