"Good enough" is an incredibly big thing. RISC-V doesn't have to displace M2/Epyc/Xeon to be important. There are a trillion cores a year being shipped in embedded devices where "cheap and configurable" is more important than raw performance. What surprises me is that we haven't seen more "built to emulate" designs yet. Many of those "trillion cores" are zombie architectures with terrible price/performance ratios, but nobody wants to rewrite their software or retool things (anything 8051, AVR or PIC seems vulnerable). I could see replacement modules using a cheap-due-to-scale RISC-V core that just emulates the old chip in baked-in firmware.
