What rail, road or bridge in the US lasts 50 years? The maintenance of rail over 6 years costs more than replacing all the GPUs in a data center, even at their current markup.
- bdangubic 6mo agohave you seen our rails, roads and bridges?!? 50 year old ones in many places are being referred to as “new ones” :) the only reason any “maintenance” on them is expensive is corruption which at municipal level rivals current administration in some places

TLDR is asset stays in good condition for 75% of lifetime i.e. decades with light maintenance (flat part of J). By roads I mean highways where most of the expense / work is in building out the base / sub base (i.e. ballasts for rail), that last decades. US is uniquely bad maintained/prevention but even then major assets do not deteriorate on GPU timeline.
