On the shoulders of giants

July 12, 2020

Robert Heinlein, claims that "specialization is for insects" in his science fiction book "Time Enough for Love":

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

 Robert Heinlein, Time Enough for Love

But, this overlooks the benefits of specialization.

How would the world of today look like if our ancestors didn't specialize? What would've happened if everybody did everything?

Would we even enjoy the most beautiful effects of our technological progress, like getting depressed due to constant comparison with our peers' overpolished photos from their current vacation?

Inherited progress

When we are born, we inherit the entire human race's progress from the past. This progress produced infrastructure and tools and utilities. And we take a lot of this for granted.

As Matt Ridley writes in "Rational Optimist," hand ax and computer mouse are both tools, but they are vastly different. A single person made the ax, and hundreds or even millions of people made the mouse. Collective intelligence, using division of labor and specialization, created a computer mouse.

The advantages of specialization

Specialization enabled the division of labor. This division enabled the production of complex objects like this computer mouse and other complex products that we use to improve our lives' quality.

Since I'm a software developer, the essential product I own is the Macbook Air. I use it to put food on the table. I know how it works and its components, but it would be impossible for me to build it from scratch. Where do I even start?

The Macbook Air is the result of constant innovation over a long period.

Specialization encouraged this innovation. It motivated people to spend time on tools that create other tools. This innovation increased the rate of progress. Tools that make tools make making tools more easy.

Specialization also increased productivity. Many workers doing one task are more productive than a single worker doing many tasks. Specialized workers produce much more. They do it quickly and with higher quality. The companies using specialized workers are more productive than companies who have workers that do everything (do these exist?).

Adam Smith said that the total output increases when one worker specializes in one activity and trades with other specialized workers. Everyone is better off with that exchange, since the production increases.

Division of labor makes sense since those who specialize in a task become more proficient in it. This depth of specialization makes building very complicated products possible, that would be unimaginable if a single person made everything.

Idea sex

To create is to recombine.

François Jacob

The division of labor is not an invention of Adam Smith. It started much more early, right after the Agricultural revolution. People started specializing, and this benefited everyone — it encouraged trade.

People initially bartered their goods and services, and money later replaced it. People needed a convenient tool for exchanging products of specializing, so money is a side effect of trading.

Trading encouraged idea sex, which increased the rate of progress. Sex plays a crucial role in biological evolution and speeds it up. What sex is to biological evolution, the exchange is to cultural development. Exchanging ideas and making them have sex propelled the culture forward and increased growth.

The idea sex didn't stop. It's very present in the modern era. Modern-day start-ups are being pitched to their potential investors as "Uber for X", or "Airbnb for Y".

Every new thing is a remix of existing ideas, from Star Wars movies to songs from Led Zeppelin [1]. PC was the remix of many things that preceded it, like the Memex and the typewriter.

If you wish to make an apple pie from scratch, you must first invent the universe.

Nothing is created from scratch, and everything is a remix. You and I included.
