How important do you think it is that there are now so many companies making real money with open-source hardware?
Doctorow: It’s crucial. There are lots of reasons that people do things, but one of the big ones is money. A culture or practice that only includes noncommercial ventures is lopsided and impoverished. I think that the DIY movement is turning into a full-fledged ecosystem with organisms that fill every niche, from giant companies to garage start-ups to hobbyists to pirates to innovators to fools and scam-artists. In other words, it’s maturing.
