Fifth generation computer systems project

The fifth generation computer systems project was an initiative by the japanese state begun in 1982 to create a "fifth generation computer" (see computer generation) which was supposed to perform much calculation utilizing massive parallellism.

To succeed in this ambitious project, billions of Yens were spent in creating specialized hardware and an operating system entirely written in prolog, as this was believed to be a truly parallellizable language.

The fifth generation computer systems project was aimed at becoming a disruptive technology but ended up as a complete failure.
