I’d just like to double down on Ben Bernanke’s comments on why he is optimistic about the future of human economic progress in the long run:

Pessimists may be paying too little attention to the strength of the underlying economic and social forces that generate innovation in the modern world. Invention was once the province of the isolated scientist or tinkerer. The transmission of new ideas and the adaptation of the best new insights to commercial uses were slow and erratic. But all of that is changing radically. We live on a planet that is becoming richer and more populous, and in which not only the most advanced economies but also large emerging market nations like China and India increasingly see their economic futures as tied to technological innovation. In that context, the number of trained scientists and engineers is increasing rapidly, as are the resources for research being provided by universities, governments, and the private sector. Moreover, because of the Internet and other advances in communications, collaboration and the exchange of ideas take place at high speed and with little regard for geographic distance. For example, research papers are now disseminated and critiqued almost instantaneously rather than after publication in a journal several years after they are written. And, importantly, as trade and globalization increase the size of the potential market for new products, the possible economic rewards for being first with an innovative product or process are growing rapidly. In short, both humanity’s capacity to innovate and the incentives to innovate are greater today than at any other time in history.

My reasons for optimism for the long run are predominantly technological rather than social. I tend to see the potential for a huge organic growth in the long run resulting from falling energy and manufacturing costs from superabundant alternative energy sources like solar, synthetic petroleum, wind, and nuclear, as well as decentralised manufacturing through 3-D printing and ultimately molecular manufacturing.

But Bernanke’s reasons are pretty good too. I see it every day. Using Twitter, the blogosphere and various other online interfaces, I discuss and refine my views in the company a huge selection of people of various backgrounds. And we all have access to masses of data to backup or challenge our ideas. Intellectual discussions and disputes that might have taken years now take days or weeks — look at the collapse of Reinhart & Rogoff. Ideas, hypotheses, inventions and concepts can spread freely. One innovation shared can feed into ten or twenty new innovations. The internet has built a decentralised open-source platform for collaborative innovation and intellectual development like nothing the world has ever seen.

Of course, as the 2008 financial collapse as well as the more general Too Big To Fail problem shows greater interconnectivity isn’t always good news. Sometimes, greater interconnectivity allows for the transmission of the negative as well as the positive; in the case of 2008 the interconnective global financial system transmitted illiquidity in a default cascade.

But in this case, sharing ideas and information seems entirely beneficial both to the systemic state of human knowledge and innovation, and to individuals like myself who wish to hook into the human network.

So this is another great reason to be optimistic about the long run.
