From the article, the goal was not to simplify, but rather to modernize:

Containers offer many benefits. To name some: process isolation, increased security, standardized logging and mature horizontal scalability.
Mightily resisting the urge to be flippant, but all of those benefits were achieved before Docker.
Docker is a (the, in some areas) modern way to do it, but far from the only way.
Increased security compared to bare hardware, lower than VMs. Also, lower than Jails and RKT (Rocket) which seems to be dead.
> process isolation, increased security
no, that's sandboxing.
So put the binary in the container. Why does it have to be compiled within the container?
