John Carmack predicts a trend towards integrated graphics, unified memory (2011)

Can you share the timestamp for that? (The whole video is an hour and a half long)

I wonder the context of the prediction, since smartphones, tablets and consoles have always followed this trend. And even Intel with their integrated graphics.

Also, on the highest-end, I don't think that will ever be the case because merging CPU and GPU creates huge thermal constraints...
