Looking at the slide someone could ask "is the Natural Language decidable"? Without any sort of restriction, the NL is NOT DECIDABLE and there are no ways to reach this property.

Using the Godel numbering by which encodes any formal language in the set of naturals number, and the Godel's Theorem of Incompleteness, there is always at least one "True sentence" that cannot be stated True or False within the formal language itself nor in ITS NATURAL INTERPRETATION.

The last interpretation function of the formal semantics box "I(MonkeyGetBanana) = F" should not be false. It should be true
