Re: "puzzles me as well..."

See below, Mr Bubble.

There is a personality type that despite great worldly success and many millions or billions of dollars, can not stop. Matt would say they have a high level of fitness and I would just label them obsessive-compulsive and very highly acculturated. These in themselves rest atop genetic success. Which is why I am not a rich man. They were, in the immortal words of Bruce Springsteen, Born to Run.

How boring is that? Where's the intellectual spirit? Learn new things -- see the world, understand it! Ah, that's the challenge.

I might as well go all the way. From Ecclesiastes
9. What has been will be again,
what has been done will be done again;
there is nothing new under the sun.

10. Is there anything of which one can say,
"Look! This is something new"?
It was here already, long ago;
it was here before our time.

11 There is no remembrance of men of old,
and even those who are yet to come
will not be remembered
by those who follow

And so with Mr. Khosla and his ethanol bubble. One can argue (I'm sure he would) that he is trying to change the world. If you or your minions are reading here, Mr. Khosla, I think you are just trying to make more money and you have fooled yourself into thinking that your actions will change the world. There is nothing new under the sun.
