The broad generalizations in Dewar's opinions are unhelpful. If you want to write software for military airplanes, then you should go ahead and learn Ada (whatever that is). If you want to build applications for the web or for "low-tech" enterprise, then you'll probably be better off learning Ruby, Python, Java et al. Both are perfectly viable ways of making a living and there is plenty of demand for both types of programmers.

In brief Ada is a safety and reliability oriented language popular in aerospace and the military. It is the official (computer) language of the US army.

Perhaps my sarcasm was not communicated properly. In any case, I'll pass on this one.
