Since Moore's 'law' of silicon scaling is irrelevant nowadays in terminology, and its terms are vague and need some papers to explain it in depth, i came up with a much simpler 'prediction'.
Namely transistor density per mm³.
Which fixes on transisors that can be fit into a area of 1mm x 1mm x 1mm.
Q: Why with the 3rd dimension?
A: as transistors and siliconwill move to 3D stacking methods soon, making this more relevant than we think.
So, my prediction in it's full glory is below.
Transistor density will double (transistor amount per mm³) every 2-3 years upto 2025 (and maybe onward).
