Although September 11 was horrible, it didn't threaten the survival of the human race, like nuclear weapons do.
From Stephen Hawking
There are too many accidents that can befall life on a single planet.
I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.
Stem cell research is the key to developing cures for degenerative conditions like Parkinson's and motor neuron disease from which I and many others suffer. The fact that the cells may come from embryos is not an objection, because the embryos are going to die anyway.
I believe the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws.
We are all different. There is no such thing as a standard or run-of-the-mill human being, but we share the same human spirit.
Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.
There is no physical law precluding particles from being organised in ways that perform even more advanced computations than the arrangements of particles in human brains.
When one's expectations are reduced to zero, one really appreciates everything one does have.
The universe is not indifferent to our existence - it depends on it.
