What's fascinating . . .is that you could now have a business that might have been selling for $10 billion where the business itself could probably not have borrowed even $100 million.

But as a private business, the company itself couldn't borrow even 1/20th of what the individuals could borrow.

Trying to prioritize among things we're unlikely to do is pretty fruitless.

Is anyone really surprised that Warren, who is the ultimate embodiment of concentrated decision-making power, picked somebody [Bill and Melinda Gates] who he thinks is like him in many important ways? It was a noble and sensible decision.

The ethical rule is from Samuel Johnson who believed that maintenance of easily removable ignorance by a responsible office holder was treacherous malfeasance in meeting moral obligation. The prudential rule is that underlying the old Warner & Swasey advertisement for machine tools: "The man who needs a new machine tool, and hasn't bought it, is already paying for it". The Warner & Swasey rule also applies, I believe, to thinking tools. If you don't have the right thinking tools, you, and the people you seek to help, are already suffering from your easily removable ignorance.
