Is brain a machine? If you don't believe in souls and that kind of thing - then the brain is material and thus a machine for me. Can you replicate the way brain works in another machine? If it is a machine than most probably yes. Can you replicate the way brain works in a digital computer? It is possible that there are physical processes going on in the brain that cannot be feasibly approximated by digital algorithms (i.e. it is possible that there are analog machines that are for some problems faster than any digital computer can be). There used to be analogue computers and it is entirely possible that some day they again will be useful. Can you build a brain without knowing how it works? Well we know how to build a brain without knowing how it works - you need a woman and a man and ... What is the definition of artificial then? Can you control AI if you don't know how exactly it works? Probably not - just like we cannot really control humans, but we have pretty good ways of influencing them.
