Are you THAT IGNORANT of history? Or just to enamored of your own opinions that simple facts are unable to get through your armor of arrogance?

When the first computers were developed they were industrial-sized machines. The primary users were the govt, major educational & research institutions and fortune 500 corporations. There was no demand in the '40s, '50s and '60s for smaller computers, and until the '60s computer engineers & designers did have the transistors required to build them, and they weren't even thinking of any applications for such devices.

Until we started going into space.
