Goals and decision making

Keep in mind, that goal is not something ultimate. Goal is more like attraction point.
There could be several attraction points.
They shouldn't conflict with each other.
But they could compete with each other. Or quite contrary --- help to each other.
Goals provide direction of learning/self development.

Feedback could be in different form.
For instance, "satisfaction signal".
Another option --- NL. But special NL parser should be able to extract key words from NL and transform them into "satisfaction signal".

Correct. AI should not evaluate hardcoded goals.
Hardcoded goals should evaluate feedback and make conclusions.
Not necessarily logical conclusions. More like emotional conclusions.

I'm thinking about implementation of simple problem solving.
You are right --- complex problem solving requires more features.
I think basic features have to be implemented first.
Basic features would help to implement simple problem solving.

Not in all possible combinations, but in "used combination".

Majority of humans' decisions are BASED on this statistical factor.
This majority consists of very simple problems/decisions though. (Like if I see "2 + 2" then I remember "4").
More complex decision making would be unavailable for this "statistical" approach. BUT(!) --- this "statistical" approach would help to quickly find limited set of possible solutions. And then more complex decision making algorithms would select right answer.
Keep in mind, that more complex algorithms are too slow and cannot solve the problem without simple "statistical" algorithm.
