You can still use the old drivers they work fine. This also isn't unique to Linux, Nvidia's latest Windows drivers also don't support 10 series cards anymore.
replyUnless the old drivers have security issues, then you're stuck with the nouveau driver which sometimes only has very basic support for some GPUs.
replyIs this the case for any hardware or are we discussing a purely hypothetical?
replyI have an old laptop with a GT 240M that's stuck in such a situation.
replyNVidia supports their GPUs for a really long time (unlike AMD, which paradoxically drops official support really fast; e.g. see their ROCm support). Anyway, by the time NVidia drops support for their current newer GPUs there's a high chance that NVK[1] will be ready for general use.
