All known public AI algorithms are just a trick.. that is why! All AI algorithms are nothing more than an endless complex mess of if-then-else statements ... just put in a different way to look different and most people think that is something magic and new and so on. It is not. At the core everything is still just a if-then-else thing. You can have as many BT, FSM, A* , UML, Neural Networks and other abstraction graph algorithms things as you want but at the core and deep down at the actual code running on silicon it is nothing more than a huge mess of if-then-else statements.
Of course anything like this can't really simulate any real lifeform even remotely. Even the most complex stuff using all those algorithms won't look real and alive anyway nor really smart. Any "smart" thing happening is just the result of mathematical algorithms and statistics at work, the whole "AI" thing is just a facade, it really is nothing more then a mechanism used to better refine data results and adjust main math algorithms parameters. And that's it. Nothing magic. Nothing AI. Nothing alive. Period.
