If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans.

Physics as we know it will be over in six months - Max Born

The fact that no one understands you doesn't mean you're an artist.

With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code. By contrast, computers double their speed and memories every 18 months. There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition.

All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.

Perhaps we could write code to optimize code, then run that code through the code optimizer?

Why are we here? Where do we come from? Traditionally, these are questions for philosophy, but philosophy is dead.
