Software innovation, like almost every other kind of innovation, requires the ability to collaborate and share ideas with other people, and to sit down and talk with customers and get their feedback and understand their needs.

The only thing I understand deeply, because in my teens I was thinking about it, and every year of my life, is software. So I'll never be hands-on on anything except software.

Microsoft Research has a thing called the Sense Cam that, as you walk around, it's taking photos all the time.

You just have that, and software helps you pick what you want.

Software is a great combination between artistry and engineering.
