What we define as a bubble is any kind of debt-fueled asset inflation where the cash flow generated by the asset itself - a rental property, office building, condo - does not cover the debt incurred to buy the asset. So you depend on a greater fool, if you will, to come in and buy at a higher price.

Dubai was a property bubble. Plain and simple. Go to Dubai and see what happened. It was... what I call it the 'Edifice complex' - it's just, we can grow by putting up lots and lots of buildings and trying to attract people to come here, stay here, and put up offices here and sooner or later, you put up too many.

There's almost 70 billion in square feet under construction in high rises in commercial, residential and light manufacturing. And we estimate about 30 billion square feet, and that's with a 'B,' is commercial, that we would just consider office space. To put that in perspective, that's a 5x5-foot cubicle for every man, woman and child in China.

The interesting thing about the China story, getting back to the macro and micro, and as dire as I think the macro story is - due to bad credit and credit extension that makes Greece and Spain and the U.S. look like child's play - when you get to the micro of individual companies, they look even worse.

Governments can make a greater effort to encourage computer science education, especially among young girls, racial minorities, and other groups whose perspectives have been underrepresented in AI.

The fact we don't have a lunar base has nothing to do with the technology. It has to do with public commitment and societal support.

It's not the music you hear in your head that other people are going to hear. You have to be able to make it true enough to the image in your head, and that's where technique and technology come in, for sure, and knowledge. It's not true and will never be true that someone who knows nothing can sit in a basement and make great music.

I've never read any of the '50 Shades of Grey' books because the Internet pre-educated me about the 'my inner goddess is doing the merengue with some salsa moves' material.
