Have you seen that study about the accuracy of chatgpt responding to programming questions? (here) It's wrong 52% of the time, and I can say that I have personally experienced trying to use chatgpt for programming and getting more confused rather than less. Maybe it is because I wasn't using gpt4, or claude, or whatever new model is the best, but I'm just sharing my experience.
Also I support electric vehicles because without them lots of energy (and emissions) is generated for critical infrastructure (we can't ditch cars yet), and so replacing that with renewably generated energy is a good idea.
LLMs consume lots of energy to train and use, but instead of literally moving millions of people around, they assist you in doing things you could have done without them, but with dubious accuracy. Look at the massive use of LLMs in by students to cheat in school, yes they may not get detected, but sometimes they have noticable flaws, that get them in large trouble for being too lazy to actually learn anything.
If you want to learn in depth knowledge about a topic, just go look it up and learn there, it's more helpful than an LLM.
