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.
