I don't think it's this, and I don't think programming is so hard (it's the business logic that is hard when you have to specify it exactingly, to reference the thread.) I think that the manufacturers of the various computers we use make it unbelievably difficult and scary to touch anything, and cast quite a bit of suspicion on you for even wanting to change anything.
