Building something that <i>isn't</i> Turing-complete is surprisingly-hard once it's complex enough.<p>If basal intelligence is present in diverse computational structures, then weak intelligence is everywhere.<p>If weak intelligence is everywhere, Earth-like planets are everywhere, ... where are the aliens?<p>Personally, I blame game theory. Too many agents too smart in one place, you get conflicts, and eventually someone breaks an atom apart in your direction.<p>Or do you need emotions to have conflict? Are there basal emotions?<p>I'm usually not worried about AI uprisings, but I do believe in the possibility of conflict.
