     Here's some more scary things to think about.

     Most of the devices that have at least a blinking LED and were manufactured in the last 15-20 years are about to start breaking down. That's because most microcontrollers and FPGAs manufactured since 00s are using memory types that guaranteed to live only for 5-20 years.

     In the days long gone, mass-manufactured devices with digital logic tended to use mask ROMs or antifuse ROMs. That made the devices cheap, and the data stored to boot them could last almost forever.

     But erasable programmable ROMs, and later Flash, became cheaper and more popular. They have benefits of being (somewhat) re-programmable, unified, easy to use, and so on. The data retention for Flash-based devices (reprogrammable FPGAs and microcontrollers) is ±5 years. Those that use EPROM (pretending to be one-time programmable ROM) can last for 10-20 years.

     Alternatives exist, but rare.
