Why Something Rather Than Nothing?

[Surgenator]

This part is incomprehensible.

A bug flies into a room through the open door, and starts fluttering about wildly, obviously hoping that these (mostly) random motions will, with a bit of luck, allow it to find the door and get back outside.

If the bug were smarter, it might be able to find its way out by thinking. But it's stupid, so it relies on the primitive random path generator to escape the trap of the room. Yet for all that, it may nevertheless succeed, which means that randomness is a form of intelligence.

Lets look at the definitions of intelligence and random.

Intelligence: the ability to apply knowledge.
Random: without definite aim, direction, rule, or method.

An intelligent processes decides by appling some knowledge learned from the situation i.e. it is using a method to decide. A random process is the opposite of that by definition.

Here is a simple example. Pick a number from -infinity to +infinity.

I can't. Without further instructions on how to narrow down the range of choices (such as "pick one of the first 43 positive primes"), there is no procedure in my mental computer that can get me to pick any one number and set aside all others.

Your missing the point. Don't think about it, just pick. If you have to think about it, it is not random.

I'm like the Buridan's ass in this case.

I have no idea what Buridan's ass comes into play. It has to deals with free will, which is not what we are talking about.
