You trust things that you can actually verify and other things you use as further research directions.

How do you know what your lawyer is saying isn’t incorrect? It’s not like people are infallible. You question, get a second opinion, verify things yourself etc.

People aren't infallible, but in my experience they're much less likely to give me incorrect factual information than LLMs. Sometimes lawyers are wrong, of course, but they are wrong less frequently and less randomly. I've typically been able to get away with not verifying every single thing someone else tells me, but I don't think I'd be that lucky relying on ChatGPT for everything.

Edit: and it's a good thing, too, because I'd never be able to afford getting second legal opinions and I don't have time to verify everything my lawyer tells me.

It's not so much the understanding of it. It's the putting together a decent summary of the issues involved such that I can make a reasonable judgement and do further research as to what to do next.

Don't me wrong, it's not replacing expertise on important legal matters, but really helps in the initiation of solutions, or providing direction towards solutions.

On the simpler stuff, it's still useful. Drafting first templates, etc.

To do the same in Google would be 30 minutes instead of 1 minute in AI.

AI first, Google for focused search, Meat expertise third
