It is a fact that humans have developed in every facet much faster after tools such as knives, mechanical advantage etc was invented. The drawback is that our minds and hands have never been able to apply these tools with consistent efficiency and quality. Welcome to the age that computers can control tools around the clock with a high level of accuracy…..
Most of us struggle to not miss the toothbrush by squeezing some tooth paste onto it in the mornings. Undoutably you might have seen 3d printing is done the same way by high accurate computing. Immagine a house being built that way…see the links below.
I noticed a theory that due to carbon time dating it is likely that humans invented hunting tools that would have led to consuming more protein by eating meat and this caused our brains to grow larger and be smarter. The facts are that the carbon dating shows that early hunting tools are from the same period as skulls that grew larger all of a sudden…interesting fact and I’m sure not the last we will hear from this research being conducted currently.
