Huddles, Clips, probably some kind of TikTok-like stories next... for me Slack has never become anything more than a good and reliable, but still a simple chat app (one of ~10 I have installed on my phone) dedicated for work.

> "In a true digital HQ, you can move all communications—even those with external partners and customers—from siloed email inboxes to channels and direct messages in Slack." Siloed email inboxes? Slack's solution is precisely putting everyone into THEIR silo/walled garden.

I'm still waiting for the EU to enforce at least some degree of inter-compatibility between chat apps. I'm tired of switching between FB Messenger, Instagram, Discord, Slack, Signal, Whatsapp, Matrix and whatnot.

Matrix supports bridges to most of these apps: https://matrix.org/bridges/
