Fun fact, Goldman built a Slack-like chat service in house that they've spun off into a company called Symphony. It's pitch is that it's more compliance-friendly for heavily regulated orgs like banks. Also, it sucks.

Splitting it in two is of course possible, but that comes with its own set of caveats in my opinion. Enterprise users have quite a different set of priorities from gamers...
Either way, I've worked at companies that don't know what they want to be, and it frankly sucks for many reasons. Good for Discord to know what they want to be.
Doesn't seem silly to me if it's working for them.
Despite having this, all the traders just end up using Bloomberg chat. GS tooling often gets in your way more than it helps.
