The programming languages you choose to learn will influence your career opportunities greatly. And if you choose the wrong one, you may lose a little piece of your soul.

While lists are abundant of popular languages, it’s rarer to find a list of the least liked languages. Recently, Stack Overflow did just this, by looking at user responses on their profiles for “Tech you prefer not to work with,” and collating the results.

Clinching the top spot for disliked languages is perl, followed by delphi, vba, php and objective c.

If that’s not enough, Stack Overflow found a coorelation between disliked languages and shrinking languages. So these languages could be going the way of the dodo.
