People make too big of a deal out of Elixir apps being less hardware-intensive.
Developers are much more expensive than hardware. Even if you have a Rails app with $5k/mo AWS bills, so what? That’s only half a developer’s salary, which is nothing.
What matters the most is developer productivity. Are your developers focusing on solving domain-specific problems, or are they implementing an authentication scheme from scratch for the umpteenth time? Only one of those things deliver value to users and generate revenue.
