So... after 2.5 years of owning a Thinkpad T400, first librebooting, then gradually modifying the shit out of it, I have to say that an Intel Core 2 Duo CPU is still completely sufficient for everything I'm doing today.
Everything packaged for Debian still runs perfectly smooth. And yes, this includes all the games.
I'm saying this because I want to make a stand against planned obsolescence and new hardware craze. Your old machine is very likely still fine. Please use it a little bit longer 🙂
@uranther The metal interconnects within the CPU itself (the metal that connects each transistor to each other) will start to atomically migrate over time, creating voids in the metal lines. Eventually you end up with one of two situations: a short circuit (metal bridging between metallic lines), or an open (a complete void in the metal line).
I'll draw a picture to give a better idea of whats happening.
@uranther @resist_berlin There's lots of failure modes in microchips too besides that. All you really need to take away is that old microchips will fail, and for consumer grade chips they design around single-digit years of life. This isn't directly around planned obsolescence, but rather a balance between good design and cost.
