Humanity has developed by leap and bounds - when we learned to
fish the new ample source of protein increased the human chance
of survival and forwarded our development, we became smarter and
stronger over time. With fire we started cooking the food and
hence made it easier to digest leaving more energy to be spent
on hunting and gathering. Again humanity increased its chances
of survival. Then came the "ages", times when technology and
methodology allowed humanity to move forward in great leaps: The
hunter gatherers moved on to the agricultural society and the
effect over time was excess food production allowing to feed a
few to spend time on thinking and fighting on our behalf -
philosophy and wars ensued. As did cities and structured
societies. With industrialisation we had another leap forward,
the productivity increase was again dramatic and the whole world
gained. Enormous excess wealth was produced, and even more
people could spend time on services instead of producing food
and goods. More healthcare,
