But ... the basic sensor technology has now run up against the laws of physics, in most areas. The main remaining problem is the one that has plagued electronics since the mid-50s: 1/f noise in the amplifiers. There are other problems, of course, of which by far the worst is the poor spectral transmission properties of the dyes used in the Bayer filters. If you would look at the low light performance of a raw sensor with only an IR cutoff filter, the results would stun you. Doug McDonald

That's what naysayers have been saying all along, yet progress continues to be made, much like past declarations that science has learned all there is to know. >The main >remaining problem is the one that has plagued electronics since >the mid-50s: 1/f noise in the amplifiers. > >There are other problems, of course, of which by far the worst >is the poor spectral transmission properties of the dyes used >in the Bayer filters.

There are other problems as well, all of which are subject to continued technological progress.
