I thought this was an excellent talk on the hard questions we should be asking ourselves as developers. Why do most people use closed, proprietary systems and devices, if the open web is so wonderful? Even as developers, we still use them ourselves, and depend on them. How can we be more empathetic to what the average user needs and wants? How can we lock open the web, so the future isn’t entirely dependent on huge corporations and services, which is where we seem to be heading?
