Yes, this a fascinating problem and will stay for decades at least. Personally, at this point in time, I would say that machine which could imitate human and make independent decisions should be considered human. Though threshold of the "independence" and "sufficiency" is very hazy. And by the same logic I don't consider newborn human kids entirely "human" for first year at least, since they obviously don't possess same level of consciousness as humans with fully grown brain (or close to it).
