Bridges as high as a kite? Yayyy...
Seriously, though,
I am serious - the Incans used rope bridges made of grass.
we need an Industrial Revolution to raise the standard of living
avoid the creation of farming, then.
Stone is out of the question. The ability of stone to be used as tools had pretty much reached its end-point by the neolithic (in both hemispheres). Quarrying, "preforming", heat-treatment , and blade making could have been (and effectively were) "industrialized" in MesoAmerica, and elsewhere but, unlike metallurgy, stone technology would not spur many associated indistries, and stone has too few uses.
the megafauna would disagree if they were still around.
let me refer you to Nan Madol. pure rock. as were many pyramids of the world.
Iron can be alloyed and cast to fullfill all sorts of functions - obsidian can't.
true, but obsidian can fufill a lot of different functions.
sure you can't melt it and use it in other fields...but then again, aside from horses, what can?
One might consider concrete as an outgrowth, but even with its ability to be poured and cast, its use would be limited. Not too many concrete airplanes and cars.
true, but as dams and walls, its pretty good.
mass manufacture. The one possible drawback is that, unlike metal, ceramics cannot be traded except as raw materials (sand, clay, shell etc) or finished artifacts.
how is that a down side? sounds like a boon.
