Just Some Opinions

I think ‘artificial intelligence’ as often understood is just the manipulation of ‘symbols’, without the ‘symbols’ having any significance, i.e. practical consequences for the computer. (This may be different for robots, I would like to hear of any difference in such cases.) Thus these ‘symbols’ are not symbols upon my definition. I do not think complex practical problems can be ‘understood’ without practical consequences. There always is too much which is just known implicitly – and cannot be fully spelled out.
