100% agreed. A lot of the cloud computing products are simply re-implementations of what was created in the Erlang/BEAM platform, but more mainstream languages. IMO it's cheaper to invest in learning Erlang or Elixir than investing in AWS/K8s/etc.

Elixir and Erlang are basically a DSL for building distributed systems. It doesn't remove all of the complications of that task, but gives you excellent, battle tested, and non-proprietary tools to solve them.
