People are so bad at driving cars that computers don't have to be that good to be much better. Any time you stand in line at the D.M.V. and look around, you're like, 'Oh, my God, I wish all these people were replaced by computer drivers.'

I don't think objectively we are in a tech bubble when tech stocks are at a 30 year low.

You are cruising along, and then technology changes. You have to adapt.

The Internet has always been, and always will be, a magic box.

People tend to think of the web as a way to get information or perhaps as a place to carry out e-commerce. But really, the web is about accessing applications.

I don't waste time being depressed.
