I'll point out that professional still cameras (DSLRs and the new mirrorless
ones) also seem to have stalled with the top-of-the-line Canon and Nikon topping
out at around 20-24 mp (after selling some models that went to 30p or so), Sony
has some models at 45 mp.
8k video is in the ballpark of 30mp
