Roman engineers were exclusively committed to material quality. I think that today's products are purposefully made to not last, so companies make profits and money moves around, heating up the economy.

that's very amazing...I remember traveling to puglia and being in a house that have 700 years and 4 floors. All made of stone and this kind of ancient concrete, not sure if the same, but amazing how it was so well preserved after 700 years and being just a pleb house. And today we have all this shit made by engineers, as they say first there was the romans being roads of stones that last until today, then came the engineers with asphalt and all this roads full of holes.

that is an interesting bite, "hot mixing" didn't know that, thanks for sharing
