If technical systems evolve according to objective laws independently on inventors and problems they choose, why technical systems in separated cultures evolved in different ways?
Why, for example, when Europeans "discovered" Far East, Polynesia, Americas, new "inventions" flooded Europe: fork, silk, gunpowder, etc. - inventioned completely missed by Europeans? Of course, there were many European inventions missed by others - those made a base for two-way trading. Some systems evolved in so different ways, that they are mystery even today, since they don't look like anything we know.
Compare different cultures' houses, villages and towns - shelter systems. Compare bridges in China, Andes, and Europe. Compare weapons used for warfare, or for hunting. Compare fishing technologies. Compare boats, kayaks, canoes, catamarans, pirogues. Agriculture tools, water supply systems, food storage systems, furniture, clothing. Musical instruments, optical instruments, writing/recordkeeping instruments. Woodcraft tools, sewing tools, cooking tools. How come objective laws of technical systems evolution drove this evolution so differently in different cultures?
