Interesting how a modern USB Bluetooth dongle is more powerful than a proper computer from 40 years ago, and much smaller as well.
If you break out of the desktop/mobile environment and into embedded, it's genuinely liberating.
Electrical engineers still write incredibly low-level code in embedded programming courses - we did some pretty interesting shit in MIPS assembler before we even touched C++ - and I doubt we were any smarter than the CompSci kids.
I think it's primarily a cultural difference - modern CompSci people love treating everything as an academic exercise and hand-waving away complexity, whereas the old-school "hackers" (before CompSci was really a huge thing) would love getting into the nitty-gritty of things and didn't really give a damn about whether or not they were following best practices.
If the average CompSci student (who, to be fair, is smart but not Genius-level) spent as much time reading the spec sheet for the Motorola 68000 as they did learning how and when a Turing Machine halts, they'd have no issue understanding 80's video game code.

Who knows, maybe they have a bunch of internal sensors and can intelligently react to high temperatures or moisture.
When GSM was invented, there was real doubt that it might not be possible to meet the very specific timing needs on the hardware that was available at the time.
I remember when we had to integrate Bluetooth into our 16 bit, 8Mhz Infineon E-gold platform. We had ~20 people working on it for 2 years.
