That statement makes the rash assumption that GPUs will somehow continue to grow in speed and complexity while everything around them remains static. What about stereoscopic displays which would double the required number of pixels to be rendered for the equivalent of a 2d image? What about HMDs like the forthcoming Oculus Rift, which over time will need to continue pushing the boundaries of higher resolution displays? Who on earth is thinking that the display industry is thinking "whelp, that's it! we've hit 1080p! we can all go home now, there's nothing left to do!" ? 1080p on a 24 inch display is nowhere close to the maximum PPI we can perceive at a normal desktop viewing distance, why is that the boundary? Why are 24" displays the end? Yes, improving technology has diminishing returns. That's nothing groundbreaking, and using that to somehow suggest that we have peaked in terms of usable GPU performance is just downright silly.

That's the beautiful thing about the scientific method. It is, by design, intended to adjust our explanations as more information becomes available. Science provides a method to *refine* our understanding of our world whereas most religious beliefs attempt to avoid new information in favor of preserving the established explanation. So think of it this way: science accepts evidence and throws out old explanations in favor of getting closer to the truth whereas religion throws out new evidence in favor of preserving old established explanations.
