Email Could Have Been X.400 Times Better | Hacker News

A Hacker News discussion argues that email and networking standards often won by being easier and cheaper to deploy than technically superior alternatives like X.400 and ATM.

The thread contrasts SMTP vs. X.400 and Ethernet/IP vs. ATM, noting that simpler internet protocols spread through incremental adoption by individual operators.

More complex telco-style systems typically needed coordinated rollouts, which raised cost and slowed adoption.

The takeaway: infrastructure standards often win on simplicity, affordability, and deployment ease, not just technical elegance.
