If you really want a language, then the two you mentioned are good. We just started using a ton of python at my company in the past 2 years for data science and AWS.
Honestly we all earn so much unnecessary money in this field that we might as well at least try to do something useful with it. The world needs less managers anyway
That's a brazen statement. How can you assume that everyone makes tons of money?
Also, where did I say that we shouldn't do something useful with our money? If you make more as a manager, that would open up an opportunity to make more of an impact.
In my experience, less managers just means pushing management duties down to people who have neither the title, nor the compensation, nor the training.
