No that is quite impossible since the future does not exist... There can be no backward causality...

In order to avoid a mystical reverse causality, it is necessary to apply feedback and control theory, as Norbert Wiener and many other people realized long ago. Essential to that approach is the existence of feedback loops with error signals that make possible gradual "homing in" on predetermined "goals."

It has to be more than some intelligence dancing about amidst the interior neuronl networks and working with information that is already present. Further information from ever-changing events and successive adaptations to those events on the outside is needed. Especially in the case of interesting human behavior, input from society and culture is crucial for intelligent planning and purpose.

Yes, that is true. It is interesting to note that, for that very reason, speculations about time travel are wholly fanciful, because it would be impossible to travel to a place that DOES NOT EXIST, even with the latest and most advanced of time machines!
