- There is always a need for low-level programming, and there is not as much development of new languages, abstractions, frameworks, and libraries in the low-level space. Indeed, most of the time you don't want any abstraction, framework or library between you and the low level thing you want to do.
- In the high-level programming space, there is a never ending race to climb higher and higher in the software stack. As such, all frameworks tend to be obsolete faster. Either it is replaced by the new high level hotness, or it gets stuck as a middle-level somewhere, below the new hotness.
Because of that, low level things don't become outdated as fast.
It could also just be that the population of Web developers is more prone to fads and churning framework after framework passing each off as serious technological innovation when they are typically just re-arrangements based on shifting opinions. So while, in this space, perhaps, “technology is changing all the time” but really it us just feverishly dog-paddling in place.
