So I just discovered that the Usborne Book of the Future has ended up online:

I remember reading that in the early ‘90s. It was fairly-dated even then - but seeing how 1979 imagined the future from 2019 is kind of wild!
Also, there are some surprising near-misses, like the wristwatch thing that is almost a mobile phone. And lots of strong AI but not much internet. (Funny how that one worked out, eh?) Then there’s the “dying planet vs green city” page, where they missed the third possibility - that we might manage to get rid of the really-overtly-ugly pollution, but do nothing about carbon emissions, thus leaving us on course for a prettier version of the dying planet.
The book is also very optimistic about human space exploration - perhaps rather more so than the intervening 30 years have justified.
Anyway, that was a unexpectedly-fascinating evening of internet browsing.
