With Crypto it was the idea of micro payments. I want to pay to read news articles, or watch a movie, or tip someone I value online, but I don't want to sign up to some monthly subscription or give over my card details. It seemed to offer a viable alternative to the advertising economy which drives everything now.
With LLMs it was the idea that I no longer have to trawl through marketing websites or endless social media posts to find the nugget of information I'm interested in. As a dev, I shouldn't have to care about responsive designs or tech stacks or accessibility or versions of node libraries, all to provide a website. Instead just pump the data directly to the AI and call it a day.
The 2 concepts could even work together so my "original thoughts" can be monetised so I can be paid royalties for my "art", like musicians are today.
