we expect software to stay up to date and keep getting better.

Well, we’ve been conditioned to expect that… Just because that’s how it’s been doesn’t mean it has to stay that way. It made sense in the past, applications were limited by the hardware’s technical capabilities, which kept improving over time - but we’ve reached a point where for the most part, the hardware is good enough to meet the needs of the software. That’s not saying it won’t continue to improve, but it’s not the limiting factor it once was. At some point, at least in theory, a product should be able to be “finished”, as in it has all the features it needs, possible exploits have been found and patched. Compare to buying tools - you don’t need to buy a new hammer every two years, well, maybe you do if you abuse the shit out of it and break it, but you don’t need to because of ongoing development in the techniques of building hammers.
