The lifespan of the GPUs used for #AI is less than three years.
IMO, scaling and oligarchical behaviour mean that replacements will be consolidated, not distributed (likely where the poor live and the politicians give generous tax breaks to polluters)
This means, before the decade is out, we will have hundreds of massive data centers abandoned. Maybe they'd be reused, but probably too expensive to do so.
We must reign in this recklessness.
