Well, personally, I think that ordinary public school pushes most kids to learn things before they're ready.
I guess that's beside the point.
But I wouldn't call it "hothousing" unless it was successful. That is, I think the term implies that kids can be made unnaturally smart or can be made to develop abnormally quickly if they are in a special environment (just as plants are successfully made to grow more quickly in a hothouse environment). I'm not sure that that is the case for children. Certainly they can be made abnormally neurotic or they can be made to perform unusual tricks...but unnaturally smart? I'm not convinced.
