  • Joseph Simpson thinks this is interesting:

ARPA’s interest in computer graphics lay in the ability to create simulations. This would be an inexpensive and safe way to train soldiers and airplane pilots. Simulation technologies are now a major aspect of training pilots, allowing them to practice dealing with potentially fatal situations. This has led directly to a reduction in airplane crashes. Other graphics of the time were devoted to computer-assisted design (CAD), scientific visualizations, and medical imaging.

Note

Early military interest in creating computer Graphics was based around what would become virtual reality simulations.
