I don't like that comparison. Email was an improvement to snail mail, and the people who you claim refused to use it just didn't understand it and didn't want to understand it.
Lots of people, myself included, understand llms and can and do use them at work because we have to, but we might choose to not use them outside of work because they rot our brains, are unethical, funnel even more money into the hands of a few billionaires (selling a service trained on stolen property) and haven't actually been proven to make the world better. Unlike email!
I’d love to read the paper on how email was objectively “proven to make the world better” and how LLMs fail this same test.
