There hasn't been enough of a market so they have not made the investment. Android occupies the lower-end side of the phone market, so there's less of a drive for the absolute highest performance. There has until very recently been almost zero desktop or laptop ARM market or server ARM market. Apple also has a ridiculous amount of cash sitting around and could afford to fund R&D ahead of market demand and develop a truly killer ARM architecture. Everyone else is now behind, but what I'm saying is that there's not much in the M1 that is secret. It's just well-understood performance CPU engineering techniques deployed well on an ARM chip and the added efficiency is largely due to the lack of X86 cruft overhead and the 5nm node.
