"When I wrote The Mobile Wave, (2012) the observation was that software networks are dematerializing everything you could hold in your hand. 

You went from taking photos on a Canon camera and storing them in a shoebox to Facebook and Instagram and the iPhone. It wasn't worth 10 times as much, it was worth 1000 times as much. The world's going to change.  

These networks [are] going to..destroy 15,000 other companies competing with them because nobody in the history of the world could ever upgrade or ship a product for no variable cost to the entire planet for a nickel. And yet, that's what Google does. That's what Facebook does. That's what Apple does. And that's the part of Amazon that works well. The conclusion was to buy Apple, Amazon, Facebook, and Google. 

I wrote the book. Nobody read it. 

I took $50 million of my own money..and converted [it] into $500 million. It made me conclude [that] if you want to make money in the tech era, you find the dominant digital network, the one that's worth 100 billion, that's crushed everybody. 

If you buy too soon, you might miss it. You might hit Blackberry, MySpace, or Yahoo. But after it’s $100 billion, the market has decided. Apple is the winner, Google's the winner, Facebook's the winner, Amazon's the winner. I know it's pretty obvious. 

Amazon was the winner in 2013 when it was trading at 300 bucks. It was funny! Everybody on Wall Street said what is this stupid company, they don't make any money. We don't buy into it. But you could have bought it. 

You could buy all those things, and you would have got a 10x - 20x gain on it. You just wait until the 99% of the world that disagrees, that’s cynical, skeptical, and ignorant, ..as it gradually dawns on them that Google is an Information Network. Facebook is a social network, Apple is mobile network, Amazon is retail network.

It made me very successful as a personal investor, but my company didn't invest in it. 2020 came and I swore to myself that if I ever saw this again, I wasn't going to write a book, I was going to buy as much of that thing as I could personally, as much of that thing as I could corporately, and then I was just going to tweet about it."
