This is one of the reasons why I think it's important we look to re-using computers, build computers with interchangeable components, and look towards designing p2p networks that replicate data around. Start designing software for newer protocols to run on low-powered machines. There are so many computers in the world it's incredible and yet they're practically built to be disposable. I don't think they can continue to increase in price forever when the network of supplies to manufacture them is so weak. And especially when climate events will be able to destroy vast quantities of them quickly.
It's surprising how much computing power is stuffed into consumer laptops these days and how people keep buying new ones when their existing ones work fine.
