Which programming language should I learn first?

There's a lot to disagree with (e.g. it's one-sided in favor of Python; I haven't rubbed elbows with software engineers, programmers, and developers let alone worked in the industry in years, but I'd suspect in general the money is mainly in C# and Java). Still, it's kind of fun to consider.
