I consider the last question in each of your examples to be unreasonable
(though for very different reasons).
In the first case, "What do you see?" is a nonsensical and unnecessary
extension on a rational chain of logic. The visual subsystem, which is not
part of the AGI, has reported something and, unless there is a good reason
not to, the AGI should believe it as a valid fact and the root of a
knowledge chain. Extending past this point to ask a spurious, open question
is silly. Doing so is entirely unnecessary. This knowledge chain is
isolated.
In the second case, I don't know why you're doing any sort of search
(particularly since there wasn't any sort of question preceding it). The AI
needed gas, it found a gas station, and it headed for it. You asked why it
waited til a given time and it told you. How is this not isolated?

It's not that we can't do it in theory. It's that we can't do it in
practice. The human brain is not a Turing machine. It has finite time and
memory limits.
