By 2030 we will have progressed to a few atoms per transistor in bulk CMOS, to wafer scale integration [3] and probably replaced most metal wires with free space optics [2]. We will see the first mass-manufactured SFQ [1] and RSFQ [4] superconducting Josephson junctions. Maybe we will see the first carbon nanotubes and superconducting circuits [5].
