We already have x86-64 (guarded licenses), ARM (less guarded but still uncertain) and SPARC, Power, RISC-V (open source).
Should a new ISA be the focus of major economic plans? Maybe if one of the objectives is protectionist ISA licensing, but that seems like an insular mistake.
An ISA ecosystem is a lingua-franca, so choosing a well established one is the most sensible basis for growing different semi/IT industry flows around.
In terms of discovering new technical benefits, new ISA's should be explored in academic circles and startups where they won't waste everyones time and money on boondoggles.

This might apply less to microcontrollers.
