I don't know about the spare time business. Hunter-gatherer societies have
lots of free time. I think the increase in population (hence, more computing
power) is far more significant. I think that continues today, and that a
significant part of current development is due to bringing ever-larger
numbers of people into our market and science systems.

Up to the invention of gunpowder, the most powerful armies were those of the
Central Asian pastoralists. Long term food surpluses can take
non-agricultural form; they used grazing animals, which had the distinct
advantage of moving themselves.
