> encryption never expires and does not care

wow, I never thought about it this way. Amazing point. Thanks.

> How could drm risk anyone's life?

- medical software - firmware on medical devices, eg people's vision implants are being turned off remotely, as well as anti-epilepsy implants, iirc - train you're taking to hospital has been turned off (trains being remotely disabled via DRM happened in Poland recently) - heated seats unable to provide warmth because you don't own DRM for a car long after the DRM servers have been shut down and copyright has lapsed. Or just because the DRM server is down right now - you get in your car to go to hospital and can't, because e.g. you bought a Fisker car which now doesn't start due to a DRM server that doesn't exist anymore after the company went bankrupt - pretty much the same thing with other EVs when they're outside of mobile network range. You have a car that works and could get you to safety, but instead you expire in the desert, and the thing doesn't even have a tank full of water you could drink - inability to repair medical devices makes them non-functional because any code fixes you could do via a disassembler are fully rpevented with DRM and TPMs - your juice press won't take your fruit pack because it's not DRM'd by them and so you die of thirst - your water fountain won't produce water because the water (!!) wasn't DRM'd, or because the server is just gone - you want to call someone for help via wifi but you're unable to because the app won't work on a jailbroken device due to DRM - you are strongly autistic and you are anchored to a specific piece of media to calm you down, and the DRM somehow becomes broken and now you can't watch that anymore and suddenly your quality of life deteriorates. you refuse to ingest foods and wither away in a hospital due to DRM

I could go on, but you get the gist. NONE of those trajectories will apply to EVERYONE, but once everything that uses electricity has DRM in it, the impact on the general population will be significant.
