Unity Technologies CEO John Riccitiello doesn't entirely agree with Deus Ex creator Warren Spector's opinion that VR is a fad.
Spector recently told Gamesindustry: "I don't think most humans want to look stupid (everyone looks stupid in a VR headset) and they don't want to isolate themselves from the world.
"I mean, if someone's sneaking up behind me with a baseball bat, I want to know about it, you know what I mean? And let's not talk about nausea."
However, former EA CEO Riccitiello, who took up the reins of the game engine company in 2014, told TechRadar that looking silly in a headset won't be the defining criteria for VR in the near future.
"He's right for the moment, but it's not because people don't want to look silly," he said. "You look silly having sex for God's sake, but they still do it - and who doesn't look an idiot dancing in the disco with the sound off?"
Riccitiello reckons figuring out what's fun or not when it comes to VR is the more pressing issue, one that he believes will become clear when mainstream laptops gain the power needed to run demanding VR games and applications.
He said: "The reality is that VR will be done in 2016 on water-cooled, high-end PCs, but by 2017 it'll be mainstream devices - and no longer a rich person's game.
The Unity boss also reflected on his own previous prediction that gaming in mobile was a fad.
"I remember when I said mobile gaming was a fad, but that was long before smartphones," he said. "Warren's an awesome guy, so I'd never want to contradict him, but he's right for 2016 and wrong for the time frame after.
"But he created Deus Ex, so he's a God. What else can I say? Even Gods can be wrong."
