"X can do Y" can be taken as a statement of fact (to which "so
what?" is an appropriate response), a desire (to which "then please
say 'make X do Y' instead" is an appropriate response), or a report
of a bug (to which "please explain why X should be forbidden from
doing Y" is an appropriate response).
This is way under-explained. I think this is "make X do Y" kind,
and if so, please say so and possibly why it is a good idea to teach
X how to do Y.
Thanks.
