You can probably extrapolate from “if it exists, there is porn of it (no exceptions)”.

P.S: What if there isn’t porn of something? Rule 35 states that if it doesn’t exist, it will be made.
AI Training, compared to crypto, has at least been used in medicine to:
Create novel proteins based on specific requirements (useful for developing medicine): https://www.cell.com/chem/fulltext/S2451-9294(23)00139-0?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS2451929423001390%3Fshowall%3Dtrue
Detect possible cancer: https://hms.harvard.edu/news/new-artificial-intelligence-tool-cancer#:~:text=CHIEF achieved nearly 94 percent,datasets containing 11 cancer types.
And there’s many more uses you can easily find if you look into it. Don’t just assume every LLM slop is all what AI is. Even LLMs probably have their use in stuff actually relating to language, such as translation.
