For a context of how microelectronics have shrunk over the years:
Originally, transistors were somewhere around 7mm wide.
One of the historical great CPUs was the Motorola 68000, which crammed 68,000 transistors into the same 7mm square.
Now we can build a M68000 small enough to fit into the space of one of _those_ transistors - ramming 68,000 M68000 CPUs into the same 7mm square.
Truly mind boogling!
Won’t this extreme miniaturization necessarily imbue these microscopic circuits with a certain fragility so that they will be susceptible to being fried by ever-smaller EM pulses? Perhaps the chip physical construction provides shielding....
