I'm not sure this correctly characterizes Linus' opinion. It seems more that he's saying debuggers cause a kind of myopia by putting a specific failure under a microscope, and that he wants developers who are willing to undertake the harder task of understanding the failure at a system level. Not that he wants to impose complexity for its own sake to cull out weaker developers.
