Many people here don't get the ironic nature of these drawings.
So, sorry to unveil this fact to you: It was just for the fun. Teacher pushing books in the crusher to feed student earphones? Underwater flying? Flying cops? All this is funny speculation that has a single purpose: entertainment. It is just like drawings of Dubout, with a scifi theme instead of cats (and a lower artistic value).
So, in makes it even more surprising that it has some relevance to today's achievement. I would like to compare with serious "scientific" forecasts of the future at the same time. I would bet they weren't as accurate as these drawings.
The presentation and style are pretty tongue-in-cheek, but I don't think that diminishes the nature of these drawings a predictions of a potential future, especially since a lot of them represent developments that actually did occur over the course of the 20th century.
