So do this just mean that the legacy CPU architectures we've been working with for decades are just really outdated?

Is this less about M1 being amazing and more about Intel being inefficient, in terms of utilization of power/speed/features?

Because I have to assume the M1 chip can ignore a host of legacy compatibility/performance tradeoffs that must exist in x86 architecture.

If this is the result, hopefully it means a more generalized leap forward (not just for Apple hardware) at some point in the coming decade..
