Some of this is unnecesary hysteria.

A new machine will always do a lot of disk writes in its first days or weeks of life as it rebuilds indexes.

Some of it also comes from swapping caused by the machine being so fast as to make us push it too hard. When I first got my M1, I regularly had several Safari windows open with dozens of tabs in each. On an 8GB machine, that's gonna swap a lot, but the machine is so fast that I seldom noticed.

When I looked at disk writes, I realized that I needed to cool my jets, so I did. Writes are much reduced now.

I bought the three year Applecare+ and will almost certainly replace the machine when that expires, but i don't think there is much chance of my running out of write space before then.

That IS something you'd want to check if buying a used machine though!
