Could "Virtual Reality" be used to make people believe they are fighting in a game when they are actually killing people they wouldn't otherwise want to kill? Maybe even for tricking military employees into murdering friends and family?
I believe it could.
I'm not saying it's that hard to talk people into becoming murder machines now, just that I think this could make things worse-- getting those who wouldn't otherwise be tools of the murderous State to kill wantonly.
That's not an excuse to ban VR, but another good reason to keep it out of government hands. Just like government should never have been allowed to have drones. Or nukes. Or guns. Or pencils. Or oxygen.
