I use LLMs. They're somewhat useful if you're on a non niche problem. They're also useful instead of search engines, but that's because search has been entshittified more than because a LLM is better.
However 90% of the marketing material about them is simply disgusting. The bigwigs sound like they're spreading a new religion, and most enthusiasts sound like they're new converts to some sect.
If you're marketing it as a tool, fine. If you're marketing it as the third and fourth coming of $DEITY, get lost.
