I wrote a comment on a German forum around 16/17 years ago that predicted how game and computer streaming services (Onlive had just been launched, there were also a few non-gaming cloud computing services for home users) could result in personal computing going extinct, because data centers providing these streaming services would buy up components, leaving nothing PCs.

I’m usually very, very wrong with my predictions, but this was my Nostradamus moment, I suppose.
