How did we get from the Palm Pilots of the 90s to the ultra-powerful smart phones of today? In large part, because of scaling, where integrated circuits are made with smaller feature sizes fitting more and more circuit elements in the same area of silicon at each technology generation. This sets our expectations that in 20 more years, our mobile devices of today will look like the Palm Pilot of yesterday. However, as current semiconductor fabrication processes are nearing fundamental limits, and the emergence of AI is driving demand for non-traditional computing architectures, new methods to fabricate at the nanoscale are required.
