Live chat is a good choice for friend and making urgent decisions in software. I've been watching projects more and more use it for their discussions, issue trackers, and Q&A solutions and it just makes me sad. Live chat isn't good for anything that will need to be revisited in the future. But still I see more and more communities moving to live chat solutions for their whole community.

And that's not to get into any of the problems with Discord specifically. I don't love giving control over community hosting to any individual company. We've already seen the results several times. Google groups? Facebook groups? Reddit subreddits? All have demonstrated the problems with hosting your communities on a singular platform. Google groups is straight up gone. Facebook groups require you to sell a small part of your soul to participate. Reddit has been outright abusive towards their user base lately. Discord is vulnerable to all these problems
