Any effort to make the death penalty speedier and less costly - more 'efficient' - will inevitably make it less just.

The death penalty and the arguments it inspires don't only involve ethics, morals, and justice. There are bureaucratic and economic aspects to it as well. All these different aspects commingle in ways that convince me we should take whatever steps we can to abolish the death penalty.

I think I have a good track record, both in commercial investing and in philanthropic investing.

The world's better off the more Silicon Valleys there are and the more scaled companies there are.

Each year, I ask, 'Now that I have this knowledge, these resources, what can I do?'
