With a token, you probably get a higher efficiency. Similar to how a heatpump is more efficient than a heater. If you only consume resources on the client side, then you hope that an attacker thinks "I won't invest $0.01 of resources just to log in here". If you also transfer the consumed resources to the server, you get an additional benefit: The server thinks "$0.01 is enough to cover the costs of a fake signup". A…
I think a fairer solution will be some form of proof of personhood that isn't PoW-based. Your idea isn't bad but it gives more power to those who can afford a lot of devices. You know those Chinese mobile phone click farms they use to game app stores? It will be like that, PoW can prevent spam only to a certain degree and with all the social media and networks we have today there is a lot of money in influencing the…
If the captcha is to prevent overuse of a free trial, then nobody will operate a lot of devices just to get more free trials if the paid version is cheaper than those devices.
If the use case is to improve democracy, then it gets more complicated.

#104I think captchas disappear next year or so. Already was soft human determination.
That’s excessively optimistic. The most likely scenario is that we’ll have captchas for the next 30 years but only humans will be bothered by them.

GPT-4 (in)famously tricked a human to do a captcha for it. The current GPT-4 with vision would probably have been able to do it without the human, but maybe it has been “gaslit” by all the content online saying that only humans can solve captchas, that it doesn’t consider it?
It’s safety trained to not solve captchas.

#106Does 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].

I cant tell if the audience of HN are more likely to script something untoward against HN, be that DDOS or just "check out my product" spam, because its a bunch of hackers - or less likely to do it because (maybe) we like having nice things, or figure the audience is too in the know to fall for boring crypto spam.

I don’t think it should be OpenAI deciding what is allowed or not though.

They go down somewhat frequently. I think it’s like four 9’s? I’m not sure why they insist on running just a few machines though. They have more than enough money and probably make up the difference by the advertising for YC that they get.
