Knowing a great deal is not the same as being smart; intelligence is not information alone but also judgement, the manner in which information is co-ordinated and used. Still, the amount of information to which we have accessed is one index of our intelligence.

How smart does a chimp have to be before killing him constitutes murder?

We are not smart enough to decide which pieces of knowledge are permissible and which are not.

Other things being equal, it is better to be smart than to be stupid.
