> So it took 10 years to ratify absolutely essential extensions?

Essential for what? RISC-V was not just created for high performance of application cores.

The first couple years RISC-V was mostly for university research work.

Turning it into a fully capable alternative only started later and yes, that takes a number of years.

> Somehow I suspect in 10 years there will be a new set of extensions promising to solve all your woes.

Its about delivering the same as Intel/ARM and they have that now. Yes, in 10 years more extentions will exist, this is true for RISC-V and ARM and x86.

> Seriously, the way to do this is for someone to just go off and do what it takes to build a good CPU and for the ISA

No it doesn't happen that way because the company wouldn't do that wouldn't open source their ISA design. Or at least not historically.

So a different path was taken to create and open standard and it worked out pretty well, even if it doesn't do what your imagination wants.
