Light in fiberoptic travels at about 0.66c, or about 124,000 mi/sec. Data on copper actually has an advantage here, travelling at 0.99c, but it’s not sustainable for long distance.
100ms being 1/10th of a second would be 12,400 miles.
The earth is about 24,000 miles at the equator.
At most, 100ms one-diredtional would be literally halfway around the world.
Of course, I have 60ms packet latency to my office 45 miles away as the crow flies. So maybe packet latency isn’t the best way to tell.



AIO PCs were and remain a terrible idea…the keyboard PC is a cool novelty reminiscent of the Commodore 64/128 era but kinda stupid nowadays. Would be cool in a C64 shell as a dedicated emulation device tho.
