This has to be wrong readings, is the M1 swapping really totally different? My normal last gen Intel Mac has 0% usage and it's nearly one year old (yes, I use it nearly daily).
It's probably macOS doing something differently when run on an M1.
From the sounds of it, the same reading they are using to suggest the M1 will only last 1-2 years has been observed on older Macs. So this whole thing seems overblown.
