Please let me ask some noob questions.

> Erlang matters today because it demonstrates how these semantics can be elegantly packaged in one language, execution model, and virtual machine.

Why is it so important to demonstrate that these semantics can be packaged into such a homogeneous environment ? Is it even a good idea ? Is this way of doing things superior to having micro-services that talk to each, all managed by a supervisor system ? Wouldn't that allow us to take advantage of the unique upsides of multiple programming languages, virtual machines and execution models ?

You may underestimate the difficulty of writing a bullet-proof and feature-rich "supervisor system". That has pretty high complexity and lots of nasty edge-cases.

Erlang happens to nail that part with OTP.
