About 15 years ago I gave some networking courses at a local education center, it was all young kids (18-20 years old). When I told them that the speed we got back in the day was 4 kilobytes per second (56k on a good day), they didn't believe me at all.
I remember using a “high-speed” 14.4 kbps modem. I mean, these were thousands of bits per second, really insane. Faster than many LLMs.
