Physicalism: A Hypothetical Future

Considering the most recent advances in artificial intelligence and biomechanics, a hypothetical future of physicalism is explored. It is concluded that a rational and sensible extrapolation of present and expected future advances in those two areas will have vast consequences in the physicalist view. In particular, it is also argued that consciousness cannot be defined in a simple general manner, but only understood through the observable and behavioural actions of humans or sufficiently advanced robots, which may be, at some future time, indistinct. This last result is established by applying what we call Plato’s trap, and our main conclusion is a defence of physicalism. It is argued that human beings are robots which soon will be indistinguishable from suitable advanced man-made robots, which will in turn render many philosophical questions and objections to physicalism irrelevant and, in fact, quite similar in sense and importance to some philosophical medieval questions about God, the soul and immortality.
