Every "future of work" startup is trying to fix Slack which was built to fix email which was built to fix meetings. At some point you have to consider the possibility that it's not the software. Maybe work is just like this. Maybe the meeting could've been an email and the email could've been nothing.
@Daojoan makes me think of the pattern where everyone once in a while the tech bros get together to try and "fix" transportation... and then disappear when they realize they've basically invented the bus.
