You may be thinking of the bugs that were present in the very first generation of M1s, that caused them to erroneously display a wear level much higher than they were actually experiencing.
And as long as you have the Silver color option, a MacBook Air from 2023 looks very much like a MacBook Air from 2014 if you're not stopping and looking closely at it.
If you have one of the colored ones, those date back to 2018 with, again, a very similar design to today's.
Except there aren't reports of that. Just tried googling and couldn't find anything about SSD failure actually happening. What I did find was some fearmongering back in 2021 about whether it might become a thing, but it seems like it was entirely hypothetical and never actually happened.
Also the M1 has only been around for a little over 3 years. They can't be dying after 4 years because they're not that old.
Where are you getting all this misinformation from? And why are you motivated to be repeating it?
