Of course now would be a good time to watch <a href="http:&#x2F;&#x2F;www.imdb.com&#x2F;title&#x2F;tt0082484&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.imdb.com&#x2F;title&#x2F;tt0082484&#x2F;</a><p>There&#x27;s nothing primitive about the things demonstrated in his videos. The self-made &#x2F; nature friendly &#x2F; survival ratio is high in my view. But I have a passion with old and simple but effective and life critical. Also the importance of geometry, you see how curves and dents will result in sub-optimal energy conversion. I&#x27;d love to find videos about gradual precision increasing and scale changes (assembling large and or small things in smart and subtles ways).<p>Chatting with people on #emacs, I learned that with long weed and time you could craft fat ropes long enough to build rope bridges. That too was fascinating.<p>There&#x27;s also a few topic on the web about bootstrapping the tech stack from scratch. Which is a fun thing to imagine too. Which leads to what alternative path could technology take, maybe there&#x27;s no need to replay history, one could quickly go into ceramics, lenses, metals and rapidly assemble radio emitters, various sensors, and (maybe?) avoid large scale agriculture, oil based devices etc etc<p>ps: this <a href="https:&#x2F;&#x2F;youtu.be&#x2F;kiHojsMTBeA?t=166" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;kiHojsMTBeA?t=166</a> is also pretty smart, how a few cross &quot;sticks&quot; leads to a natural frame for a basket. How to derive structure and strength from weak bits of plants and trees.
