Thermodynamics
Brute-force attacks against 256-bit keys will be infeasible until computers are built from something other than matter and occupy something other than space.

Dr. Aubrey de Grey in Israel
Dr. Aubrey de Grey (Aubrey David Nicholas Jasper de Grey to be exact, age 50) came to Israel for the first time to take part in the 8th European Congress of Biogerontology organized this year by Ben Gurion University of the Negev.
Utopia, the Tel-Aviv International Festival for Science Fiction, Imagination and the Future, organized an informal lecture and Q&A session with de Grey in Tel Aviv, to which I had the privilege to join.
The first part of the lecture was dedicated to a short description of de Grey's research on regenerative and preventative medicine to thwart the aging process (his work at the SENS Research Foundation). The rest of the lecture was based on questions from the crowd about radical life extension.

"One word of notice before we begin, all the the technologies you're going to see here, now, are real..."
- Dr. Ido Bachelet: The emergence of nanobot society, TEDMED Israel 2013
Nano-robots that fix tissues and control drugs have been envisioned for over 30 years. Now, using DNA origami and molecular programming, they are reality. These nanobots can seek and kill cancer cells, mimic social insect behaviors, carry out logical operators like a computer in a living animal, and they can be controlled from an Xbox. Ido Bachelet from the bio-design lab at Bar Ilan University explains this technology and how it will change medicine in the near future.
God, No!
Penn Jillette draws a sharp line between beliefs preserved by tradition and knowledge anchored in reality and repeatable discovery:
If every trace of any single religion were wiped out and nothing were passed on, it would never be created exactly that way again. There might be some other nonsense in its place, but not that exact nonsense. If all of science were wiped out, it would still be true and someone would find a way to figure it all out again.
As Richard Feynman put it decades earlier:
The test of all knowledge is experiment. Experiment is the sole judge of scientific truth.
