Epic Games CEO Tim Sweeney thinks that photo-realism in games is not too far off, but he thinks larger AI issues still need to be dealt with. GameDaily has the story.
"We simulate character facial animation using tens of bones and facial controls, but in the body, you have thousands. It turns out we've evolved to recognize those things with extraordinary detail, so we're far short of being able to simulate that," he continued. "And unfortunately, all of that's not just a matter of computational power, because if we had infinitely fast computers now, we still wouldn't be able to solve that, because we just don't have the algorithms; we don't know how the brain works or how to simulate it."
