This happens in every research community. The hero worship also tends to over-fund certain areas because of how the agenda is effectively set by a few researchers.
One way that may help fix this is if there's a way to generate a crowd-sourced network of links whose purpose is to plot as a graph the current gaps and challenges of the field. It's perhaps easier in fields with clear subject boundaries like physics.
We could then observe how individual knowledge contributions have helped (are helping) progress the growing knowledge "surface." Young researchers could also observe areas of neglect and attack those instead of going where everyone else is. Reward people who grow the knowledge surface, irrespective of their background.
