Well the thing is, photorealism actually can be least - or at least we can imagine what reaching it would look like.  A Start Trek-style holodeck, completely indistinguishable from real life, would be true photorealism.  I highly doubt we&#x27;ll reach that point in any of our lifetimes, but that&#x27;s where we&#x27;ll eventually end up, if gaming technology continues to improve indefinitely.
