Why do some companies use outdated programming languages?

There’s a company in my city, and they are almost always looking for fresh out of college software engineers. When I look at the requirements they always say that they use programming languages like Fortran, Ada, Ruby on Rails, etc. Why don’t companies switch to high-end technologies? Why are they stuck on ancient languages?

They have massive applications that need support. It’s not easy to rewrite millions of lines of code. They want to hire maintenance programmed to take care of those ancient apps. Odds are they have modern languages as well.

Martin Taylor I know that they’re over 30 years old, but they are still being maintained... I didn’t know that these languages too were being maintained because I never heard anyone (besides my CS teacher) saying that they used them.
