I think what has changed the most about our relationship with technology now a days compared to prehistory is the overall incentives for technology changing. It used to be technology had to actually improve something to be adopted. A bow and arrow was superior to throwing a stone, so it was adopted on merit. Sowing seed and animal husbandry was superior to migrating around seasonal harvest from uncultivated flora and game, so it was also adopted on merit. No one was marketing this shift.

Meanwhile we have a lot of technology where its only incentive is not to be thermodynamically easier to an alternative, but to make someone money. Sometimes the technology is even less efficient than the alternative, but its perpetuated and expanded and iterated upon because it is so lucrative. I think once we hit this point with technology is when the singularity really kicked off. Not recently or in the future but potentially in the time of Ea-Nasir and his ingots.
