Google translate isn't the key or the answer either, it's constantly slightly wrong, but it's still useful because you can combine it with your own partial understanding to get the right translation.
It feels like you're either missing or ignoring my point entirely here, I'm not saying use Google translate for the legal document, I'm giving examples of how imperfect tools can still help you get to where you need to go. You're saying it's completely useless because sometimes it's going to be wrong, I'm just saying that's an un-nuanced take. Yes if they're signing a contract, absolutely get a lawyer if you don't understand what you're signing, but occasionally you just need to look up a law or accept a eula, and it would be nice to be able to have some help reading it, even if it's from an imperfect tool.
