The Raspberry Pi in all its invocations was conceived as a filip for education about computer systems but looking at some of the recent posts in these NGs, it seems to have got stuck in a blind alley; the alley of Linux, whereas the real education about computers and how they work is down at a much lower level.
This lamentable state of affairs seems to be extant in recent so-called "computer science" graduates who have no inkling about how a computer works and could not design from scratch themselves a computer because thinking, as they do, that the world of computing is made up from Linux, C and C++.
An acadaemic education should not be about current commercial convenience lest you end up with degrees with no acadaemic characteristics such as sports science and tourism management.
