The evaluation of programmers isn't nearly as objective as the evaluation of athletes, and I'm not convinced modafinil and amphetamines have a statistically significant advantage (how much does programming ability even matter for getting ahead anywhere?), let alone a ludicrous one. On the other hand, the advantage from steroids is ludicrous on multiple factors including stamina, recovery, strength etc. The advantage from cheating and lying in the science game is also very high in my experience, although difficult to measure.
