We aren't slowing down, we are going back to normal levels of development. For the last 20 years we've been rushing and agiling everything for the sake of money, sacrificing backwards compatibility and maintainability. Reusing old devices is a given. A program works until an update breaks it. The hardware is perfectly suited for this - x86 has ridiculous back compat. The challenges you point out are completely self made and it's time we repay our technical debt. As far as biosphere goes, it's like saying a slow dentist harms surgeons. What even is this mythical software which protects the biosphere and lifts people from poverty? SV is not contributing to such efforts, nor is any general SE corporation. We will just slow down and consume less software. Less, but better maintained.
