I think it's important to recognize the article does not suggest any obvious user-facing changes to how email operates; only technical ones that would hopefully fix the many pain points there.
All the behind the scenes failures are also a feature. Diffusion of responsibility, plausibly deniability. No one needs "mgmt" to be able to nail their coffin easier than they already can.
99% of the world doesn't work in HN land of high pay for high expectations. Most places are trying to force people to work 100hrs a week for as close to min wage as possible.
Unless countries start enacting actual labor laws with teeth I stand by my statement that no one really wants or needs email to work better, there already are alternatives.
