Agreed. The article sort of presents these kind of "computer problems" as a barrier to getting started with programming. I don't quite agree -- or maybe they are, but only in the sense that they "filter out" those who don't really want to be programmers at an earlier point in time.

Don't get me wrong; I don't think there's any point in making new programmers jump through arbitrary hoops because "programming should be hard". But I think that today, programming is necessarily intertwined with computing and problem-solving in general, and all the Dockers and specialised positions in the world don't change that. To be a good developer, you need to have some idea about the systems your code will be running on. A program doesn't just exist in a bubble. (This is more true for some kinds of applications, less for others, of course.)
