I had a MacBook once that lasted for 13 years, and that's what I used to assume people meant by "crazy good lifespan".
Once on this site I saw someone talking about how the lifespan is so good they only had to replace their MacBook every two years instead of every year, and it just made me realize "crazy good lifespan" is meaningless.
Not necessarily meaningless, but maybe relative, i.e. a person who generally replaces non-Apple laptops every X years would replace MacBooks every Y years, with Y > X
