Generally speaking macOS is extremely write heavy for all sort of reason even before the switch to ARM. But in majority of case if should last 4-5 years without problem.

The heavy write bug Apple said was due to misreporting and was fixed ( so they say ).

I do think you should pay attention to it from time to time. iCloud Sync, Spotlight, Safari heavy tabs are all known to cause heavy paging in some corner case. You might end up having a TB of data written for no apparent reason. Apple used to ship their Macbook with MLC, on a 512GB MLC you could do 500TBW without problem, that is ~13 years of usage if you do 100GB write per day. Not sure about the M1 machines.

If you are doing Dev staging, Video and photos editing a lot these drive will fail quite quickly. In the space of 2 - 3 years. Although some would argue MacBook Air are not made for those task. And especially true if you have 8GB and 256GB NAND.
