Go people might cringe but why wouldn't you just be 100% Rust?
Actual response: Some similarities, different goals, different strengths, different abstraction levels. Go is cool I hear but I don't see a need from over here doing Elixir.
In a concurrent environment Go is not guaranteed memory safe, leaving you exposed to silent errors of value ... which for Fintech is just suicidal.
Because we live with our past decisions... All new services are in Go. The elixir service serves us well still.
Curious: why did you move from elixir to go ?
Why not 100% Elixir, since it is more robust and uses less resources?
