I'm a little short sighted, but I don't wear glasses.
So even 5 megapixels is actually higher resolution that real life (for
anything beyond a meter or so), for me anyways.

4K is 8.4 Megapixels, so I think Brad is right in that 4k should be
enough for any human.  After reaching 4k I think the only thing that
makes sense is going towards VR/AR.

Technologies have a tendency of plateauing after they reach market
saturation. For instance personal computer shipments peaked in 2010 [1]

Also audio resolution hasn't really gone above 24bit.
While some sound calculations to avoid rounding errors happen in 32bit,
recording and listening resolution is pretty much maxed out at 24bit.

Consumers usually are completely satisfied with 16bit.
The difference between 16bit and 32bit audio is almost imperceptible.
