For me, the most serious problem is how America became so vulnerable to the assertion of blatant falsehoods that drive policy and are not corrected by the so-called immune system of democracy, a free press and a free democratic discourse.

The Pacific Yew can be cut down and processed to produce a potent chemical, taxol, which offers some promise of curing certain forms of lung, breast and ovarian cancer in patients who would otherwise quickly die... It seems an easy choice - sacrifice the tree for a human life - until one learns that three trees must be destroyed for each patient treated.

I have a sense of mission on this climate crisis, and I'm trying to pour all the energy I have into it. And I hope that I, along with others, can catalyze the emergence of real solutions to the climate crisis. I think we're making a lot of progress. I think we're going to win this, but it matters how quickly we win it. So I'm focused on that.

All I have to do is be the best Al I can be, because I'm good enough, I'm smart enough and, doggone it, people like me.

The answer is to end our reliance on carbon-based fuels... If we succeed, we create booming new industries, wealth, clean secure energy and maybe we prevent the greatest disaster so far in human history, saving millions of lives while improving billions more. If we fail, basically it's business as usual while things slowly get worse all around us.
