"Twenty years ago if I had been paid to convince an audience of reasonable, educated people that in 20 years time we'd have street and satellite maps for the entire world on our personal hand held phone devices -- for free -- and with street views for many cities -- I would not be able to do it. I could not have made an economic case for how this could come about "for free." It was starkly impossible back then.
These supposed impossibilities keep happening with increased frequency. Everyone "knew" that people don't work for free, and if they did, they could not make something useful without a boss. But today entire sections of our economy run on software instruments created by volunteers working without pay or bosses."
I love Kevin Kelly.
