Literally the entire thread appears to be "people who can't do maths correctly, misinterpreting a third-party tool which may or may not be accurately reporting the information in the first place, running around like their hair is on fire."
Apple's own Activity Monitor shows hundreds of GBs of disk writes per hour on my M1 Macbook Pro. Smartctl output showing 10+ terabytes of writes per month looks about right. Apple doesn't provide lifetime TBW numbers but e.g. Samsung seems to only cover about 150-250 terabytes written total for various 250GB SSD models.
