Most of the big breakthrough technologies/companies seem crazy at first: PCs, the internet, Bitcoin, Airbnb, Uber, 140 characters.. It has to be a radical product. It has to be something where, when people look at it, at first they say, ‘I don’t get it, I don’t understand it. I think it’s too weird, I think it’s too unusual.’

I love what the Valley does. I love company building. I love startups. I love technology companies. I love new technology. I love this process of invention. Being able to participate in that as a founder and a product creator, or as an investor or a board member, I just find that hugely satisfying.

An awful lot of successful technology companies ended up being in a slightly different market than they started out in. Microsoft started with programming tools, but came out with an operating system. Oracle started doing contracts for the CIA. AOL started out as an online video gaming network.

Technology is like water; it wants to find its level. So if you hook up your computer to a billion other computers, it just makes sense that a tremendous share of the resources you want to use - not only text or media but processing power too - will be located remotely.

There's always more demands than there's time to meet them, so it's constantly a matter of trying to balance them

The good news about building a company during times like this is that the companies that do succeed are going to be extremely strong and resilient.

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