Every time you go to sleep and then wake up, you can never be certain that you have woken to reality, or were drugged while asleep and then inserted into a VR contraption.
You could wake up and walk to the office and engage in a meeting discussing corporate confidential secrets only to realize that you were in a VR machine and just gave all your company secrets to a competitor.
Similar scenarios if you have important knowledge or you're just a wealthy person with a Swiss bank account.
It will be some time before that happens and there might be countermeasures.
Some of this was gone over in Inception and other sci-fi movies/books/etc.
This all plays into the current notion that we all might be part of some sophisticated computer simulation.
VR within VR within VR.
Interesting to contemplate, but generally more depressing than illuminating.
More like: standard neo-luddite hysteria.
I’ve seen it for decades over nearly every major new technology.
Conceivable yes, but practically preposterous.
