It's even more improbable. For both of those, your starting to see more and more of the current generation that are children/nieces/nephews of the already famous. They have the financial comfort to pursue it, and the family connections in the industries.

Those were two fields that seemingly were still meritocratic, but that is fading fast, if it ever existed at all.
