As far as larping goes, quantitative finance is currently the hottest field for that. I'm sure that close to 100% of the people on social media that market themselves as quants are in fact not professional quantitative analysts / researchers / developers.
They all post vids of their vibe-coded dashboards where agents are doing market research and executing trades, while they kick back as collect to profits.
I've even seen these people promote some ASICs for home use, you know, to get those extra milliseconds shaved off.
After tech layoffs started, the get-rich-quick folks looked on what other fields pay well, and the decided that the absolutely most selective, the most credentialed and gatekept niche role in finance, that's the one to impersonate.
