Will 30 series owners upgrade, like they did from the 20 series which was just a terrible for RT? You had a £1099 card that was then made redundant by the £469 3070 if all you are interested in is DLSS/RT.
Isn't it the same thing you are asking, the re: the longevity?
I'd love to know what the situation would have been like in the consumer focused gaming market had it not been for these shortages, I mean you saw people dumping those 2080 TI's for under £500 on the MM for a while, almost in a panic about how much they had been screwed over, which funnily enough was due to the fact RDNA2 existed and for once AMD would be competitive with Nvidia again, regardless of the RT function.
Personally (not a gamer anymore really) unless you include strategy games where graphics count for 1% of the game, but it seems like I am living back in the SNES/Mega drive days when people would argue over which console had better graphics, in other words pointless stupid playground arguments, except this time it is being held by grown people, not children, I think.
