A tougher question as so many factors that I hope Asianometry on YouTube cover one day.
Whilst the RISC-V instruction set is free from licence/patent fees, the design of those chips will be made by a company that will need to recover costs, so there will be a cost. Compared to ARM who already offer up free core designs for use for free like the cortex-m0 and others. I know the Raspberry PICO uses a cortex-m0x.
Though, many do seem to blur the lines between the instruction set and the core design you get in the chip you buy.
Over time, but that will be when you get open-source RISC-V chips that compete with the designs of the market offerings other companies make and sell. Which as a mindset may cause the evolution of RISC-V issues as people could get burned due to expectations exceeding the reality and finding the get what you pay for those to still hold stronger than envisioned. Yes, eventually open-source CPU cores will get there, but production costs and scale will still become a factor, as to many aspects that all add up to the final cost. This is even on a level of software stack tried and fully robust of equality, which is still behind ARM.
ARM may well kill off x86 as a mainstream before RISC-V fully bites it.
Look at how long ARM took to get where it is, and started with microcontrollers, used in many things. That is where RISC-V will and is starting to get traction, but scaling beyond that, whilst could be faster than ARM's history, it's not as clear-cut as many foresee.
