I listened to part of this talk, which may be found here:
The remark that Jose alludes to occurs at the end of the first video clip
and the beginning of the second video clip.
Voevodsky was pointing out that CIC has an infinite list of operations and
axioms, which he regards as not "clean" since he prefers a finite list.
As far as I can tell, this was a taste judgement, and he was not
suggesting that CIC might be inconsistent, or that proofs based on CIC
might be unreliable.
