I would argue that ideas are cheap until they are proven correct, relatively, compared to the effort to proven them, in some cases, also to apply them into real world scenarios. I see the society give unproportionally large credit to the so-called "leaders", because they pioneered certain "ideas". That's wrong. Histories bury too many talented individuals who are not recognized, because of some pioneers are frantically sucked all the attentions the society can give. In professional research community, authors are listed because they are deemed a critical contributor to the work. Plain and simple.
