I tried to explain pretty much that ⬆️ to an acquaintance last week. Not even two sentences in, I was met with "oh shut up and stop talking nonsense", repeatedly. I kept explaining (to the rest of those present) a simplified version of how LLM training works, and said person kept interjecting telling me I knew nothing and to shut up.
The reason? They use ChatGPT at work "daily" and it's so amazingly fast and it provides "sources". When I pointed out those sources are often wholesale false, they said "well you have to check them of course!", but declined to answer my question what the advantage of ChatGPT is if you have to do all the reading yourself anyway (probably because they don't actually do that).
People's opinions on LLMs have become one of my go to metrics to judge someone's character at this point, because someone who's unwilling to engage with factual arguments that run counter to what they want to believe is, frankly, a danger to everyone around them. Today it's ChatGPT worship, tomorrow it's climate change denial and anti-vaxxing. Because anyone who spends even an hour learning about what's under the hood of an LLM would be thoroughly disenchanted with the frauds who push that shit onto everyone.
