Look at the historical precedent and the people that have contributed the most to human knowledge. There is no shortage of examples. Even Google would not have been possible without academics. If you want to argue the opposite side then we can agree on definitions and you can bring up examples of industry leaders that have contributed in some significant way to human knowledge.

You have not even come close to defending your point that 'academia is the only place that true learning happens'.

All you did was give a justification that academia is a place that learning happens. In fact all that is needed to prove you incorrect is ONE counterexample.
