(and frankly, it likely will only need to work until the bubble bursts, making "the long run" irrelevant)
Now I get why people are so weirdly being dismissive about the whole thing. Good luck, it's not going to "burst" any time soon.
Or rather, a "burst" would not change the world in the direction you want it to be.
As soon as the investment boom is over, this will be largely gone. LLMs will continue to be trained and data will continue to be scraped, but that alone isn't the problem. Search engine crawlers somehow manage not to DDoS the servers they pull the data from, competent AI scrapers can do the same. In fact, a competent AI scraper wouldn't even be stopped by Anubis as it is right now at all, and yet Anubis works pretty well in practice. Go figure.
