An excerpt from a post by economist Tyler Cowen on Marginal Revolution about the merits of amateur efforts:
“Amateurism is splendid when amateurs actually can make contributions. A lot of the Industrial Revolution was driven by the inventions of so-called amateurs. One of the most revolutionary economic sectors today — social networking — has been led by amateurs. Maybe it is stretching the concept, but you can interpret Bill Gates and Steve Jobs as amateurs too.
Amateurs are associated with free entry and a lot of experimentation. Barbecue quality is very often driven by amateurs, and in general amateurs still make contributions to food and cooking. The difficulty of maintaining productive amateurs is one of the reasons why scientific progress periodically slows down. Specialization, however necessary it may be, can make big breakthroughs harder at some margin. This is one aspect of the division of labor which Adam Smith did not fully grasp, though he hinted at it.
Through computers, and the internet, the notion of amateurs working together is becoming more important. This includes astronomical searches and theorem-proving, plus collection and collation of data, and Wikipedia; this is Shirky’s ‘cognitive surplus.’”
