If the GCC compiler has an issue, I'm in a lot of trouble too, even though it's open source. I guess I could scan the code and figure out any minor problems (or figure out why I was misusing it) but I'm not an expert in compilers, or even at tensor programming.

Obviously it would be better if they're open source, since someone would be able to fix them, and it helps to know how your tools really work. But a better closed source driver is probably the right tool for most problems.
