> You need something with traction

No language has traction, until it does.

It would be fair to point out though that Ada has had decades to catch on and replace C, but it hasn't done so, except in certain narrow areas of highly critical embedded software development in aviation and military applications. My understanding is that it's not easy to work with for 'general purpose' work (command-line applications on GNU/Linux), as it lacks mature bindings.

I think it's fair to say Ada failed to truly embrace Free and Open Source software. A pity, in my opinion.
