I think what OP is suggesting isn't so much that Pis will use M1 chips, more that right now typically many applications are unavailable as prebuikt binaries for arm64, and maybe having more arm processors in the wild will make that situation change. I just switched to the starship shell prompt on my mac, for example, and I tried to install it on my Pi as well, but there's no prebuilt binary for Pi, and after an hour or so I gave up trying to build it myself. :P
