Could you clarify? Are you using the typo as this basis, or something else?

There were 2 typos in that sentence (the one I didn’t mention is “fully” instead of “full”). Talking about intelligence in such a sloppy manner sounded like a joke to me.

I'm not the same person, but probably. There are at least two errors in the quoted fragment, though personally I don't think either is especially indicative of a lack of intelligence.
