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

If you wanted to build the most powerful computer you could, you can't do better than including everything in the universe that's potentially available.

The amount of information that can be stored by the ultimate laptop, 10 to the 31st bits, is much higher than the 10 to the 10th bits stored on current laptops.

Nothing in life is certain except death, taxes and the second law of thermodynamics. All three are processes in which useful or accessible forms of some quantity, such as energy or money, are transformed into useless, inaccessible forms of the same quantity. That is not to say that these three processes don't have fringe benefits: taxes pay for roads and schools; the second law of thermodynamics drives cars, computers and metabolism; and death, at the very least, opens up tenured faculty positions.

All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of.

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.
