I agree with what you are saying, and probably it is part of the nature of progress to continually move some of the core topics out of the realm of CS common knowledge to make way for the new. However I think not all things are created equal. For instance, I think basically everyone can agree that moving from assembly to C and other high-level languages was basically a strict upgrade, and obviated the need for assembly programming in all but a few specific use cases. By contrast, using the command line and shell programming is every bit as relevant as it was 20 years ago, and I don't see that changing any time soon. Both assembly and the shell are difficult and alienating to newcomers. But learning is mostly academic at this point, while learning the other opens up entire new worlds in terms of what you can do with a computer. In other words, learning assembly is like learning latin. Maybe interesting, but not particularly useful. Learning bash is like learning Chinese. Not particularly easy, but there's a lot you can do with it right now.
