The article concludes that to make the game more physically realistic, you'd have to have place a finite budget of processing power on the character's brain since being able to think indefinitely while the rest of the world stayed frozen would require a near infinite amount of processing power.
The trailer for Lucy, a new action movie starring Scarlett Johansson, posits what might happen if a person could use 100% of their brain instead of just 10%. But we might need far more such brain capacity to achieve what is shown in The Matrix or Superhot.

I was at Amazon when Jeff Bezos banned Powerpoint. Some say it was because he didn't like thinking to be bent and twisted to fit into the tyrannical, atomized slide-by-slide nature of a Powerpoint deck (this is the Tufte argument). But having been in meetings with Jeff, I also think that he was so smart that as soon as anyone started presenting a deck Jeff would just flip ahead in the presentation and finish reading it before you'd even completed presenting your first slide. He would grow bored and impatient waiting for you to unfold some pre-constructed narrative; he'd rather inhale the ideas and get on to debating them.
Writing our ideas out in prose was the only way to get enough of a head start on Jeff's brain to slow him down to the same speed as everyone else. For those dead silent ten minutes while Jeff sat reading your essay, it was as if you were the Flash and time in the world around you had stopped.
