Upgrade our downgrades
So we are creating computers using lots of different materials and then we eventually have to throw them all away when a new operating system is released, how is this going to work for humanity over the next few thousand years? Where's all the material trash going?
Originally we started just picking up rocks and chipping them to make an axe, then throwing them away when we figured out how to put the little bits on the end of a branch to make a spear ... these days we're digging up tons of materials, using heat and chemicals to start to make new CPU's ... overall heating the planet a little more when the data gets larger and travels faster with a new computer needing more power before we upgrade and throw it away, needing more work and heat to build the new one.
