I have genuinely found LLMs to be useful in many contexts. I use them to brainstorm and flesh out ideas for tabletop roleplaying adventures, to write song lyrics, to write Python scripts to do various random tasks. I've talked with them to learn about stuff, and verified that they were correct by checking their references. LLMs are demonstrably capable of these things. I demonstrated it.
Go ahead and refrain from using them yourself if you really don't want to, for whatever reason. But exclaiming "no it doesn't!" In the face of them actually doing the things you say they don't is just silly.
Ukraine has invaded Russia and seized more Russian territory in the past five days than the Russians have managed to take from Ukraine in months. Seemingly with very little effort or casualties.
