The hardest technological barrier to overcome is production and casting of high grade metals at scale. All the primitive tech guys on youtube have an easy time with everything until it gets to making a furnace capable of smelting iron. That's difficult as all hell and then building all the parts and the ore supply chain to scale that up is a very long process. Once scalable metals production gets going, one can progress to chemicals and then to electricity and to optics to semiconductors eventually.
- theandrewbailey 8y agoOne of the points everyone ignores is agriculture. If you're going to have a bunch of humans in a small area (civilization), it's going to be a requirement. Until you have mechanized/highly productive agriculture, more than half of your population's job will be food production.
