In 1900, the German chocolate company Hildebrands released a series of souvenir postcards depicting an imaginary world of the 2000s. This is how the future was imagined just 100 years ago.
It strongly resembles our propaganda posters.
They are so naive.
On the other hand, I think that if someone had shown me a micro SD memory card just 20 years ago and said, "There are 128 gigabytes here"... I wouldn't have believed them at the time. I wouldn't have believed then that it would be possible even 20 years later.
Well, there are laptops that are more powerful than my desktop, although I didn't believe that either.:D
