The thing about testing is that each time you produce a new kind of tester you have a chance to find bugs in the blind spots of the previous testing approaches. Diversity makes sense, more so than in software construction.

Yeah that was my bet, escaping the local minima imposed by the current state of fuzzing. I am seeing this problem as statistical and information theory problem. Some day someone by chance will create another fuzzer that would find more bugs because of the blindspots in the previous generation including mine.
