Do you know how much you could do in a month but can't because of bad design choices, overengineered type systems, and dogmatic adherence to the 'every application needs to be written in the language with the best benchmark numbers' myth?
False dichotomy. The real solution is a language with a strong, static type system (and thus plenty of room for ahead-of-time optimization) that's also concise and productive, such as Kotlin or Swift.
