Klaus FrankLooking at https://www.youtube.com/@htme it apparently takes a very small group of people only about 10 years to make it from scratch to quite a surprising amount of todays technology.
I kinda expected them to not even make it half the way in that time. But apparently if you know what you're building it is millennia faster than when you don't...
How To Make Everything
Today, getting what you need is as easy as a trip to the store; from food to clothing, energy, medicine, and so much more. Andy will discover what it takes to make everything from scratch. His mission is to understand complex manufacturing and production processes that are often taken for granted, doing it all himself. Each week he'll travel the world to bypass the modern supply chain in oder to harvest raw materials straight from the source. Along the way, he’s answering the questions you never thought to ask. Andy is learning How To Make Everything! Thank you to our patrons for making this series possible!
