imo if they really started from first principals they would have not simply built another email client. They started with all of the "problems" that already exist in email and did a good job of improving those. this is a 1 -> n improvement.
If they really thought from first principle and the "problem" they would have made a 0 -> 1 improvement in communication protocol. Although this is a much harder problem to solve. Not that what they did isn't valuable, but imo there's more to be done here
