The first sentence seems fine (humans are somewhat obviously just on the cusp of general intelligence, in evolutionary terms).

The second sentence starts with a "perhaps", so isn't trying to present itself as fact, though agree is still overstated. My best guess is it's about right (I think 5% is somewhat of an underestimate, but not like massively so).

Seems like a reasonable criticism to me of the post. Standards for posts on LessWrong are mostly just like normal blog posts, though people try pretty hard to be precise in their guesses (hence the use of 5% in the above, which I think by people not used to LessWrong communication norms reads as making a reference to an established fact or scientific study or something).
