The principles of parallel computing, and how they work at hardware and driver levels are more broad. Some parts of it are provincial (Strong province though...), and others are more general.

It's hard to find skills that don't have a degree of provincialism. It's not a great feeling, but you more on. IMO, don't over-idealize the concept of general-knowledge to your detriment.

I think we can also untangle the open-source part from the general/provincial. There is more to the world worth exploring.
