> There are not very many systems one could conceive of that could do useful work 1/s for ~every human on the planet.
Roughly a hundred servers on 100 GbE ports each could handle one small UDP packet per human every second, and would have a plenty of cycles and RAM per human left to actually do some work.
That fits in a shipping container.
Illustrative of course: the point is that "for every human" is not far out there given how crazy powerful hardware has become.

While there is no correlation between the Visa claim of 70k tps to people on the planet, there is also no correlation to the number of servers needed to process UDP packets.
The "Visa network" is more of a trusted collaboration between a small number of banks operating multi-step transactions than it is an OSI Layer 1 - 5 concern.
