So this whittles away AIXI and similar formalisms from the possible
candidates for being a pgpps.

Even an AIXI needs a "safe" environment to start with, just like a human
baby.  It would only be after it had learnt the basics of how its environment
works that it would become truly super powerful.

When thinking about how powerful an AIXI is I think it is useful to make a
distinction between a "baby AIXI", and a "mature AIXI" that had learnt about
its environment.

While AIXI is all a bit pie in the sky, "mathematical philosophy" if you like,
I think the above does however highlight something of practical importance:
Even if your AI is incomputably super powerful, like AIXI, the training and
education of the AI is still really important.  Very few people spend time
thinking about how to teach and train a baby AI.  I think this is a greatly
ignored aspect of AI.
