I like the way someone described a similar retort:
Anyone can build a bridge that stays up and lasts a long time, but it takes a skilled engineer to build a bridge that just barely stays up a long time and minimizes costs and materials.

there’s a difference.
their engineering was amazing, but to compensate with lack of modern maths, they build with a much larger margin of safety and strength.
that’s why some of those aqueducts last 2000 years.
no one wants to build infrastructure that lasts so long. we could build a bridge designed to last thousands of years, but it’ll cost way way more, and the budget isn’t unlimited.

100% not a joke, that is the point.
Also our bridges are subjected to the insane forces of truck freight transportation. Who know how long they would last otherwise.
They were designed for that (usually), if you want a bridge to last multiple millenia you can design it for that. but it will probably add a couple zeroes at the end of the bill.
Romans had the ‘advantage’ of slave labour,
Interestingly enough, construction wasn’t a usual avenue for applying slave labor in Ancient Rome.
really?
Did they paid professionals to do that? I understand masons, but not the actual putting a big brick on top of another
like musical instruments, bridges are meant to be stressed. gotta drive over em with trucks or they’ll shoot off into space
It’s also worth pointing out those structures aren’t subjected to a lot of freeze thaw cycles, not to mention almost no salt.

I wish things weren’t always so short-sighted by default. I mean sometimes things evolve so maybe it’s better to leave room for teardown and improvement or whatnot.
But it seems if you’re not thinking in “quarterlies”, infrastructure that’s built once and simply maintained should cost a lot less in the long run.
But then I guess the contractors would dry up if they didn’t have to come rebuild it a dozen times a decade. :p
Yhea, it is better to build infrastructure that lasts, but 2000 years?
that is a bit overkill, and more of a vanity project for billionaires which is more of a cry for help (by help I mean guillotine)
I feel, for the hard to replace stuff an interstate bridge in a dense city for example, aiming for a three digit life span should be considered. Just because it kinda sucks having to replace infrastructure like that. And the city is most likely still going to be there and need that infrastructure.
Golden gate is almost 90, empire State building also approaching a 100,
I think we can do that.

And even if we could, Autocad crashed again so I can’t

just use msPaint, more reliable
