This is the achilles heel of modern tech. Devices are just so brittle and if it is not online 24/7 on returning back online, you need to perform incantations to get things working.
Long shell life is a taboo in the tech world where 5 years is a long time.
That was my initial reaction as well, when I first found the device not being able to update. But look what was the saving grace: SSH/USB/HTTP/Unix with root access, instead of closed systems, hardware that you own 100%.
As software is increasingly "solved" by AI I think this is what will become most important
Yeah it's kind of comical the framing is that a device needs to be "revived" after four years. As SWEs we should probably all be a bit embarrassed for our trade, even in the alleged golden era of LLM induced productivity.
I have all sorts of offline digital&analog mechanical/optical devices which just work decades and decades later. The weak point in any of my old tech is when theres a software component that needs to be reverse engineered and ported across multiple generations of CPU architecture / OS / API deprecations.
I have 60 year old records, 35 year old CDs, 25 year old minidiscs that all still work fine. Properly developed film negatives are still fine decades later.
Despite all the warnings about media impermanence and lifespans, it's always the software that screws it up first. I've lost more content from digital / streaming services because it simply vanishes than because a piece of physical media failed.
