I think to truly advance this discussion in good faith (as opposed to just as a general snow against e-waste concerns), you have to look at the full lifespan story. Like, yeah, that computer that's 10 years old maybe shouldn't be running any more, but do the gains associated with annual replacement justify the production and e-waste cost of all the intermediate ones? What about a 2- or 3-year replacement cadence? How does the calculus change if the computer is being operated somewhere where it's cold most of the year and so the "waste" heat still has a useful function? How does it change if throwing out the computer also means throwing out a battery and screen, as is the case for laptops and phones? Does the extra mass of a tower pay for itself in terms of longer lifespan as people upgrade those systems piecemeal?
