Given the fact that it is used beyond web programming to do just about everything where performance doesn't matter.
But from a "build a new product" perspective, Python is losing to Ruby, Go, and JavaScript.
Python is only winning a few niche markets like numerical computation, statistics. and biology...which most developers are not in. If you are trying to learn a language to get a job, you're probably not wanting to look at small niche industries to work in.
Of course you can build billion dollar companies in any language, but that wasn't the question or comment being discussed.
I understand that I really need to learn to program by picking "any" language.
I get paid a good six figure salary right now and I am not in programming. I would like to "lessen" the transition time to become a developer by paying a tutor and getting a couple hundred hours into learning and then quit my job and make the jump.
