What do mean by stolen technology? I haven't been closely following the development of the Rift.
Palmer Luckey didn't invent VR. nor does he claim to invent VR. The current VR revolution is a convergence of a lot of long-standing technologies that only became viable at a consumer level all at the same time. VR is not an invention created by one man, but rather a convergence of multiple inventions.
Palmer Luckey was one of the first modern inventors to put all the pieces together, but it's built on the fundamentals of VR that have been defined since the 80's. In essence, he's the one who figured out how to put it all together for cheap. For comparison, a Virtuality Pod in 1994 cost $65,000, not including the computer. An Oculus Rift can be had for under $700.
Additionally, early in the development, Valve lent their research to John Carmack and Palmer Luckey (and Sony) under the guise that a rising tide raises all ships. When Mark Zuckerberg bought Oculus, the pitch they used to sell him the company
wasn't the oculus rift. They didn't show him their current (at the time) DK2 prototype, but rather they showed him
valve's prototype:
Zuckerberg bought Oculus with the intent of them making Valve's prototype into a consumer product. They tried to buy Valve's VR team from Valve after buying Oculus, but the vast majority of the VR team remained at Valve.
Either way, it's dumb to allege that he stole technology or is just a bumbling businessman. The guy has been in EE subcultures for over a decade, he's not a flash in the pan and fly by night venture capitalist.
Yeah, don't believe Zenimax. You clearly haven't been following this. Zenimax's claims are bullshit. The "technology" Carmack "stole" was a mod of Doom 3. Zenimax has nothing to do with the current round of VR.
