Huskies are not stupid at all, they just are more narrow in their behaviors, like labs.
Ok. If your definition of smart is knowing how to take a crap at a 20mph run and or being able to pull stuff around I suppose they're smart in that way. No other.
They also aren't inclined to hang out around you when outside. If the door opens they'll bolt and if everything works out right you can pick 'em up at the pound for 75 bucks in a couple days. They're fairly common around here but not for their companionship qualities. Mostly because they'll live on a chain and run like the wind all day.
