In the 1940’s William Gibson used ‘cyberspace’, in his 1991 sci-fi tale “Burning Chrome”. “Mathematical hallucinations” are the domain of computer networks in which a specific person is created: he chose it after some deliberation as a cool-sounding phrase to describe the domain of connected computers.

As for finding the word ‘controlled-space’, something about it is really bad. And it’s basically just a phone call. When I think about him, he is an outstanding performer of his own people, and his name has stuck.

I highly recommend Burning Chrome, or indeed any of Gibson’s work, the Sprawl trilogy particularly (Neuromancer, Count Zero, Mon Lisa Overdrive) (which were an inspiration for the Matrix movies, with Mona Lisa Overdrive being the name of a track from the Matrix Reloaded soundtrack)

If the verb is active to form the imperfect tense and you use “would” instead of “used to” you can use “would”

in this case.

My comment, “i wouldnt do this if it weren’t compulsory” (no comma is required) is also very correctly used.
