Here's a piece from yesterday's Mercury News. He's not a pure investor. It's part philanthropy:

I think the probability of humanity living longer is greater if we're a multi-planet species. I think that's fairly obvious. But I'm also quite optimistic about Earth. I don't think Earth is in any danger of imminent demise. I think we will solve the problems that we have before us, and that humanity will probably live for a very long time.

But there's always a chance that it could end. That's why people buy life insurance. They don't expect to drop dead tomorrow. Or car insurance. You don't expect to T-bone your car into a semi. But you might. That's why I'm a big believer in space exploration.

For me, space exploration is actually more interesting for positive reasons. I think humanity will be far more interesting and richer and diverse and just the future will be much more exciting and interesting if we are a space-faring civilization that is expanding among the stars than if we're forever on Earth.

That's the attitude I'd have if I had his kind of money.

Jewish mothers have known this for millenia. When all is said and done, its really all about the children.

And, as I have been saying for years, the only definition of spacefaring that matters is whether we can safely and routinely bear and raise children "out there" somewhere -- whether on the Moon, or on Mars, or in O'Neill free flyer colonies, or wherever.

I am primarily a "Mars guy" because I believe Mars is the second safest location within our solar system to settle down and raise a family.

Translation of that article.

Making money building rockets is a lot harder and less profitable than I thought it was (and the other guys doing it aren't as stupid as I though they were) and therefore I am redefining what success is so that this does not look like another in the long line of failures of launch vehicle companies.

It seems to me, skeptic, that we happened to read a different article. Or did you read the article at all? Your first line should say:
"My opinion of that article, without reading it..."
