Can you tell me why time travel is impossible and computers human behaviour not?

Why the Decarte's problem is dubious? I don't want your opinion, I want an explanation.

Well, that is a fine line if I ever heard one. Now, did Eisstein think about relativity or did he create it? Hmmm ...

For me, when I create I think and when I think I create. Unless of course who ever created the computer was thinking.

I know humans will give computer sensors. We are more intelligent than the computer, that is why. Humans and roaches can adapt. Much, much more intelligent than computers, which are just little programs that do the same thing over and over again. I know AI people want to make it more than that. That is how they get research grants.

I'll take the intelligence of a cockroach over a computer any time. While you may be enamored by a piece of metal that cranks out stuff very fast, I am more enamored by a species that has successfully managed to preserve itself for millions of years. It is a matter of taste, I believe.

But I think those little neural, supercycle computers with advanced TNT operating systems have a ways to go. They cannot understand simple English sentences yet.

Can you tell me why time travel is impossible

Personally, I do not find an equivalency between the two.

I can do all sorts of things that I like to do, that a computer can't do. For example, ride a bike in a park.

But, I would not be surprised if there are people who would rather sit around cranking out numbers for their whole life, and I think a computer mind is a fine idea for them.

But brains are computers......

Is there a microsft emblem on the inside of your skull?:whistling:

Of course you don't: you've ignored all the troublesome facts and evidence.

Read what you just wrote, and imagine that it applies to you. Pretty revealing isn't it? If you cannot see the differences between a computer and the human brain, I sure won't be able to help you out.

S: (n) computer ...... a machine for performing calculations automatically

A machine for performing calculations automatically ...... can you guess what the brain does? (protip: numbers are involved)

Your taking that the Computational theory of mind as if it is a fact and actually saying the Brain manipulates number's is patently false, rather that the mind is a symbol manipulator that follows step by step functions to compute input and form output.

All along this you havent proved even stated an arguement for the Computational theory of mind rather than just asserted your position

Numbers are symbols

Other symbols can be encoded in terms of numbers

You see this happen whenever you see a JPEG or hear an MP3 recording

I know numbers are symbol's but there not the symbols that the human brain use's if it in fact does work as the Computational theory of mind suggests but earlier you presented the brain as if it was some number crunching machine, which is a misleading analogy.

It's not a misleading analogy. It's not even an "analogy". It's the neurological fact. Not only is every neuron like a threshold gate, it is a threshold gate.

Oden, would you like to replace your brain with a man made one?

Sure, as long as I have evidence that it will work at least as well if not better than the original, and that the operation has a minimal chance of failing.

What would make me feel better is an incremental cellular level take over: take a pill every day, the artificial neurons find their way to the brain, look at the real neurons for their threshold, kill the old ones, take over, and so on. If any failure crops up, I can consult with the doctors and scientists before anything gets seriously screwed up.

The possibilities with poking around in the nervous system are virtually limitless. If I get a head injury, it can be repaired immediately. I could back up the contents of my brain. I could have a photographic memory. I could run through symbolic logic proofs effortlessly in my head, etc.

Hey, fantastic. So I can assume from your answer the bottom line is to live longer. Right?
William

To a certain degree, but the main thing is to have a higher quality of life.

Good answer. Everyone wants a higher quality of life. Now let's say you are right. Now we have 10,000,000,000 plus people on the planet with man made brains living say 50 years longer and loving it. Man we are using up resources like it is going out of style and having kids out the kazoo, ripping their brains out at birth cause hell, who would want the old dilapidated one. Before you know it there's 20,000,000,000. Now I know you see where I am going with this. Before you know it the planet is depleated. Now what?
