I think that Parent made the observation that it is sad that in our information society people (in responsible positions (regarding ICT)) don't know about the fundamentals of the information society. At least, that's what I took from it and I concur.

We, as a society, should have started integrating computational thinking (Wing, 2006) as a core competency in the k-12 curriculum from the late 1980s onwards. We didn't.

anecdote

In 1991, I was in 5th grade, I saw the first computer enter the classroom in my primary school. It wasn't used but for some remedial mathematics training for a students or two and I believe the teacher did a computer course with it.

In 2010 I became a high school computer science teacher. There were three computer rooms (about 30 computers each) for the whole school (of about 1500 students) running windows XP + IE 6. Besides my class, the computer rooms were mostly used for making reports and "searching for information". Some departments did have specialized software installed (most of which came with the text books), but used it sparingly at best. On top of that, these software was mostly simple, inflexible, mostly non-interactive, non-collaborative, and "pre-fab" instructional materials. Often this software was not much more than a "digitized" version of parts of the text book with some animations, games, and procedural trainers mixed in.
