I agree but it needn't inherently be this way, I think it's mostly influenced by the incentives of the site. Asking questions about X very specific thing on Y very specific version of Z specific technology should have answers that can be correct forever, as well as being very searchable. However, the setup of the site is such that questions like that aren't rewarded, for all the reasons we are familiar with. Instead effort and attention tend to funnel towards very generic, high level, sometimes even tech agnostic questions that accrue hundreds to thousands of upvotes and orders of magnitude more views. Unfortunately for these, the 'right' or most appropriate answers of course very much moreso change in time.
