It's a mistake to assume that the utility of a tool has anything to do with its adoption.

The real barrier to adoption for any tool are the network effects of other existing tools which create attention barriers and cultural barriers which may hinder adoption of superior alternatives.

A tool has to adhere and build on top of existing conceptual baggage in order to be appealing to the masses of developers.

This is partly because developers believe that the tools they're using now are cutting-edge and optimal... So a radical conceptual reinvention of their current favorite tools will look to them like a step backwards, regardless of how much further it can take them forward.
