“I wish the country had fewer lawyers and more engineers.”

“As president, I believe that robotics can inspire young people to pursue science and engineering. And I also want to keep an eye on those robots in case they try anything.”

“Scientists and engineers ought to stand side by side with athletes and entertainers as role models.”

“I stand here knowing that my story is part of the larger American story, that I owe a debt to all of those who came before me, and that in no other country on Earth is my story even possible.”

“In the face of impossible odds, people who love this country can change it.”

“But you see, a rich country like America can perhaps afford to be stupid.”

“I've never been more hopeful about our future. I have never been more hopeful about America. And I ask you to sustain that hope. I'm not talking about blind optimism, the kind of hope that just ignores the enormity of the tasks ahead or the roadblocks that stand in our path. I'm not talking about the wishful idealism that allows us to just sit on the sidelines or shirk from a fight. I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting.”
