Everyone should be using Matrix. Not just open source developers.
It's near feature parity with Slack and it's also one of the best IRC clients around. I used to run ERC in a tmux session just so I could stay connected and not lose messages. No more.
The ease of bridging is great. We've got a minecraft server bridge of all things; being liberated to actually have universal chat is the future for sure.
Yes, Matrix has great momentum. It is somewhat sad that XMPP is falling behind. There is no technical reason, why Matrix should be superior, but they are winning.
