So very bloody true
@Fact Finder. I believe it is time the world stops it’s fascination with making transistors smaller, in order to get speed improvements, and looks elsewhere. And I agree that that elsewhere should be Akida.
At 3nm, transistors are only 15-times the size of a Silicon atom (0.2nm). Surely we are getting to the limits of both manufacturing and also down to sizes where quantum effects start to come into play.
I believe 28nm, or even 22nm, is a nice sweet spot for silicon to operate in. This can be produced economically by many manufacturers, and has inherent heat transfer and robustness advantages.
There is some talk about photon based transistors, which theoretically can be 20 times faster than silicon transistors employing electrons. But due to the wavelengths of light involved (1.3 micro meters —or 1300nm), the transistors necessarily are at about 100-times larger than even 22nm technology.
