Had Mother Nature been a real parent, she would have been in jail for child abuse and murder.

The cognitive functioning of a human brain depends on a delicate orchestration of many factors, especially during the critical stages of embryo development-and it is much more likely that this self-organizing structure, to be enhanced, needs to be carefully balanced, tuned, and cultivated rather than simply flooded with some extraneous potion.

In the next century, we will be inventing radical new technologies - machine intelligence, perhaps nanotech, great advances in synthetic biology and other things we haven't even thought of yet. And those new powers will unlock wonderful opportunities, but they might also bring with them certain risks. And we have no track record of surviving those risks. So if there are big existential risks, I think they are going to come from our own activities and mostly from our own inventiveness and creativity.

There are some problems that technology can't solve.

The challenge presented by the prospect of superintelligence, and how we might best respond is quite possibly the most important and most daunting challenge humanity has ever faced. And-whether we succeed or fail-it is probably the last challenge we will ever face.

Knowledge about limitations of your data collection process affects what inferences you can draw from the data.

Far from being the smartest possible biological species, we are probably better thought of as the stupidest possible biological species capable of starting a technological civilization - a niche we filled because we got there first, not because we are in any sense optimally adapted to it.
