I'm not going to disagree that they're often, and have to be to stay alive, clever - but very strongly disagree that, as you are insinuating with this that they are Intelligent; there is a difference, however thin. If they were intelligent they would know how to use the cleverness and would not Hack. Plain examples of cleverness without intelligence happen all over the place - even around me! Even, in Year 8 we took a Maths Test; and someone beat me (AH!
); he got Lv 7.6 and I got Lv 7.4! Now, he's brainy and I will give you that - but he had no ideahow to use it, and all Year he sat there just to the right of me (we were sitting in order of grades, bit nasty on most people) then when SATs came I in no uncertain terms whooped his arse. I have no idea what he got but I got 8.4 and the next one down to me was not him but only got 7.8! So he actually managed to stay at the same level for a Year and a Half!
Thats my point. Do not confuse cleverness with intelligence; there is a difference.
