Learning and using multiple languages is absolutely vital to being able to choose the right tool for the job. You have time to learn both and switching is a necessary skill if you want to program professionally

> to learn both and switching is a necessary skill if you want to program professionally

There is a hoard of professional Java or C# developers that invalidate the idea that you need to know more then one language to program professionally.

While this might seem odd to a hn reader, where there is weekly blog posts of comparing languages or trying out the new shiny thing at a startup.

One need to remember the audience is single digit percentile of the computer industry. The rest of the industry actually use jdk or .net in the enterprise.

My advice is sound for anyone working as a programmer because it gives them more options. Many of those Java/C# devs are stigmatized in a mold and will have more trouble applying to jobs outside large enterprise.

My last job was for a small startup.

They used Java. The rest of my programming jobs, -large and small, has been either Java, PHP, .Net and once a bit of Delphi. Lately there's also been a lot of TypeScript.

There's been a few jobs I wanted to apply for but couldn't because I'm not good enough with C/C++ and Qt.

Maybe things are different in Silicon Valley but around here the most exotic language I see is Python.
