> I guess I disagree with your premise then? In my experience someone who is likely to think that anyone can learn CS is likely to also think that anyone can learn art, car repair, or chemistry.

That isn't my premise. My premise is that saying such a thing isn't a bold claim, it's a commonly accepted claim.

When you said "This is a bold claim", I replied with "I disagree", because "Some people just aren't any good at $DISCIPLINE" isn't a bold claim.
