Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?
This is your opportunity to ask questions. No question too simple or too silly.

Notes -
I think you're making the mistake of thinking of the human species as a unified entity. It's true that humans are the dominant species on the planet, but some humans are more dominant than others. Henrich argues that inter-tribal competition is a major engine of technological progress, and that this often comes in the form of cultural evolution which in turn has a knock-on effect on biological evolution. Tribe A figures out a new method of preparing food which makes its members more likely to survive to adulthood and have children compared to Tribe B, and over time Tribe A outcompetes Tribe B, passing on this method of preparing food to its descendants. This obviously affects Tribe A's biological makeup (see: rates of lactose intolerance in Europe compared to Asia).
Once again, I don't see why any part of this process necessitates that the entities be conscious. If you have a species containing multiple competing tribes (and even neighbouring tribes of chimpanzees go to war with one another) and they develop some way of passing on information from one generation to the next, all the ingredients for cultural evolution and hence technological development are there.
I'm not sure what your point is. Probably this happened to us at some point in our evolutionary history. I just reject the idea that it was preordained. Consciousness achieved fixation in our species because it gave us a competitive advantage in our specific evolutionary niche, but in a different environment it might never have happened.
Right but, again, I assume the roads weren't empty of other cars, right? You still had to respond to novel stimuli in the form of other vehicles on the road, even while executing a repetitive task.
