Any new technology tends to go through a 25-year adoption cycle.

I've been a customer of the top venture capital firms, so I know exactly what they do and don't do.

On the back end, software programming tools and Internet-based services make it easy to launch new global software-powered start-ups in many industries - without the need to invest in new infrastructure and train new employees.

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

Start-ups should be based on radical ideas. There should be a high failure rate for start-ups, because if there isn't their ideas aren't bold enough.

Big breakthrough ideas often seem nuts the first time you see them.

The difference between a vision and a hallucination is that other people can see the vision.
