Look, any sufficiently complex autonomous system necessitates a bigger, more complex one to maintain it's functionality. The more complex, the harder it is to deal with the entropy that this system is removing form it's target action area.

Eventually you need a whole universe capable of sustaining self reproducing intelligent systems. The way to get intelligent autonomous and sufficiently complex systems to do anything non trivial is life.

Anyone trying to sell you a box they say is capable of non trivial, adaptive, complex behavior autonomously is selling you a perpetual motion machine: a pretense that thermodynamics can be suspended at will.
