Taking into consideration how long it's taken the ARM industry to get a single decent laptop/desktop processor with the M1 since ARM64 was published. And it's y

  ARM started at a time when Moore Law still hold strong. It was much harder to catch up. The incumbents can't double their products performance every 18-month anymore. So RISC-V can have a easier time catching up than ARM did, one hopes.

    What's the reason the law no longer holds? Physical limitations or Intel just busted with their research?

      During a CPU cycle the entire chip needs to stabilize; new voltages come as inputs and some time is required to stabilize the outputs to the correct values, this time cannot be lower that size_of_chip/speed_of_light and it is already quite close, but the chip cannot become much smaller as the transistors are already at an atomic scale. Breakthroughs are now architectural, like if someone figured a way to implement a CPU with half as many transistor we could get a ~30% increase in clock frequency
