“I just want to point out this fact: In the universe, an important mark of a civilization’s technological advancement is its ability to control and make use of micro dimensions. Making use of fundamental particles without taking advantage of the micro dimensions is something that our naked, hairy ancestors already began back when they lit bonfires within caves. Controlling chemical reactions is just manipulating micro particles without regard to the micro dimensions. Of course, this control also progressed from crude to advanced: from bonfires to steam engines, and then generators. Now, the ability for humans to manipulate micro particles at the macro level has reached a peak: We have computers and nanomaterials. But all of that is accomplished without unlocking the many micro dimensions. From the perspective of a more advanced civilization in the universe, bonfires and computers and nanomaterials are not fundamentally different. They all belong to the same level. That’s also why they still think of humans as mere bugs. Unfortunately, I think they’re right.”

#3—What would I do/have/be if I had $10 million? What’s my real TMI? In 2004, I was doing better than ever financially, and BrainQUICKEN was distributed in perhaps a dozen countries. The problem? I was running on caffeine, working 15-hour days, and constantly on the verge of meltdown. My girlfriend, who I expected to marry, left me due to the workaholism. Over the next 6 months of treading water and feeling trapped, I realized I had to restructure the business or shut it down—it was literally killing me. This is when I began journaling on a few questions, including “What would I want to do, have, and be if I had $10 million in the bank?” and “What’s my real target monthly income (TMI)?” For the latter, in other words: How much does my dream life—the stuff I’m deferring for “retirement”—really cost if I pay on a monthly basis? (See fourhourworkweek.com/tmi.) After running the numbers, most of my fantasies were far more affordable than I’d expected. Perhaps I didn’t need to keep grinding and building? Perhaps I needed more time and mobility, not more income? This made me think that maybe, just maybe, I could afford to be happy and not just “successful.” I decided to take a long overseas trip.

A fourth factor was the two-way link between the rise in human population density and the rise in food production. In all parts of the world where adequate evidence is available, archaeologists find evidence of rising densities associated with the appearance of food production. Which was the cause and which the result? This is a long-debated chicken-or-egg problem: did a rise in human population density force people to turn to food production, or did food production permit a rise in human population density? In principle, one expects the chain of causation to operate in both directions. As I’ve already discussed, food production tends to lead to increased population densities because it yields more edible calories per acre than does hunting-gathering. On the other hand, human population densities were gradually rising throughout the late Pleistocene anyway, thanks to improvements in human technology for collecting and processing wild foods. As population densities rose, food production became increasingly favored because it provided the increased food outputs needed to feed all those people. That is, the adoption of food production exemplifies what is termed an autocatalytic process—one that catalyzes itself in a positive feedback cycle, going faster and faster once it has started. A gradual rise in population densities impelled people to obtain more food, by rewarding those who unconsciously took steps toward producing it. Once people began to produce food and become sedentary, they could shorten the birth spacing and produce still more people, requiring still more food. This bidirectional link between food production and population density explains the paradox that food production, while increasing the quantity of edible calories per acre, left the food producers less well nourished than the hunter-gatherers whom they succeeded. That paradox developed because human population densities rose slightly more steeply than did the availability of food. Taken together, these four factors help us understand why the transition to…
