How do people willing to make statements like "the future of email is X" not understand that the decentralized standards based federated network is the end goal for an electronic mail system?

If you think the use case of twitter type messages isn't going to eventually be similar then you either think twitter style communication is a fad or you think the tech community is going to stagnate and never move on from how to send short messages to each other.

Maybe that eventual standard will expand to replace email, but twitter? That's so silly it's in Poe's Law territory.
