Why is email so hard to kill? Because too much economic activity is dependent on it.

The reason Slack managed to steal the "internal comms" segment from email quite easily is because there's no economic activity there.

A doodler and computerer. I like permissive/permissionless open source, smart contracts, p2p systems, room-scale VR, and NixOS.

i don’t know if that comparison then tracks to PMF 

Slack combined internal collaboration tools in disparate pillars of the org

email is ubiquitous across a multitude of biz lines/pillars

I'm mainly pointing at the phenomenon where corps that adopted Slack substantially reduced their internal email usage. In that sense, Slack consumed some subset of email use cases.

But obviously it made no dent in other use cases (external comms).

Email as a protocol is fine doesn't mind losing internal comms (no loss of economic activity), because it's external comms that is keeping it alive: That's where all the economic activity is.

If another protocol takes away email's economic activity the way Slack took away email's internal comms, then email will finally die.

Might be temporality. 

Slack provides now the ability to archive and have a much more cohesive conversation. 

Agreed initially all internal based just fyi comms

Email continued to provide a seamless protocol deliverable. 

You don’t need to OAuth to send one to another vs Slack’s
