Comment on It must have been a whole lot more difficult to design and build tall buildings before computers existed

In the book “The World Without Us” the author states that old steel bridges would be among the last human made structures left thousands of years after humas have dissapeared for the reason that they didn’t have strenght calculations back then which they solved by simply overbuilding everything.

I won’t believe for a second that they didn’t have the ability to calculate strength.

Hmmm, not sure. I feel like stone erodes slower than steel oxydizes

    Interesting. Any particular reason the channel tunnel would last longer than say the Gotthard?
    
    I guess the gotthard is in the alps so landslides and rockfalls?
