1 hour in Java

My indirect experience with python is that it is slow as hell. Anytime I install an app that includes python it lags 15-30 minutes on that step. Anytime I’m asked to install something with conda it takes 30 minutes to an hour.

I’m sure that is just due to environmental and implementation issues, but the Java fans say the same thing…

It’s near-universally regarded as a great prototyping language. For prod you should use something big-boy, like Java, or if you want to get fancy, Rust.
The “Big Boys” use tests to gauge when code is production ready, they don’t rely on a typing system and call it a day. I’ve seen monoliths made out of bash serve their purpose for years without a glitch, thanks to tests.
Tests are good too, although you can go overboard. You can write tests in Java or Rust or similar.
