A lot of that I base on, "Is it still going to sound interesting and fresh to me in five years, am I going to be embarrassed by this in five years?" It's easier for me to do stark, moody, pretty stuff, and I have all this pop stuff inside me, but it's a lot more dangerous, and pop is just apt to sound contrived and sort of pedestrian if you're not careful.
But there's still so much you can do with technology to improve the customer experience. And that's the sense in which I believe it's still Day One, and that it's early in the day. If anything, the rate of change is accelerating.
