Android’s lead user interface designer aims high
What motivates you professionally?
The biggest motivation is trying to advance the state of human-computer interaction. The basic paradigms for interacting with computing devices and information are still crude and incredibly primitive, because the nature of operating systems is to become monopolies and ossify very quickly. There is not a lot of evolution in the ways that people try to interact with stuff. Like the fact that you have to save files. Or even have the concept of files. There are just so many of these absurdities in the way that people are expected to interact with this incredibly powerful, promethean technology. Mobile is the best opportunity—our last, best hope, as it were—for breaking out of the patterns of the desktop.
