What is Sustainable Computing? A shift in how we develop the hardware of the future

They make motherboards that can have more than one CPU on them. But consumer CPUs don't have the ability to be used more than one on a board unlocked. And, in any case, this only works if all the CPUs used are identical.
Imagine if you could upgrade to the newest generation of CPU by buying one, and plugging it in to your motherboard while keeping your original CPU, so that they would both work for you. And then in the next generation, plug in a third one, only having to get a new motherboard after four generations - without wasting a single CPU until then.
