When it comes to their capacity to screw things up, computers are becoming more human every day.

For hundreds of millions of years, Sex was the most efficient method for propagating information of dubious provenance: the origins of all those snippets of junk DNA are lost in the sands of reproductive history. Move aside, Sex: the world-wide Web has usurped your role.

There are considerable advantages to using many degrees of freedom to store information, stability and controllability being perhaps the most important.

Another feature that everybody notices about the universe is that it's complex.

[With quantum computers] you can calculate how many bits are in the universe, how much energy it takes to flip them, how much energy exists, and use that to rule out lots of things about the universe's history. Anything that takes more bit flips couldn't have happened.

Yes, I am a quantum mechanic! Those darn quantum computers break all the time.

Instead of having to be a member of the Royal Society to do science, the way you had to be in England in the 17th, 18th, centuries today pretty much anybody who wants to do it can, and the information that they need to do it is there.
