This is a most excellent place for technology news and articles.
I'd put building cathedrals and pyramids more on slaves than worship of deity... other than that, spot on.
And he singles out recovering rockets as a feat of engineering, not space exploration, which would've been my second quip.
Pyramids being built by slaves was debunked long ago. Cathedrals also weren't lol.
Egypt didn't use slaves to build the pyramids. They used paid skilled workers. We have their living areas and pay receipts. You are working with outdated information. Cathedrals cover a 1700 year period and multiple labor strategies. I'm sure some were built with slaves but the majority weren't and slavery was all but absent for the majority of the period unless you count serfdom, but serfs didn't have the skills to build them so they don't count.
Neither where build by slaves.
