I dunno about that personally. He's a great/the greatest shooter but I think with the way the game is trending you'll also see the impact of more emphasis on the development of the 3pt shot in the coming years - I think it'll be something players will have and practice earlier and harder. They might not reach Curry's peak as far as being a pretty well rounded player and excellent shooter but I think we'll actually see some players approach him in terms of consistency/accuracy - maybe a next generation Kyle Korver type.
Kyle Korver-level marksmen have been around for a couple decades (even before then, but not as high-efficiency). It's much harder to do it as a primary scoring option, and that's partly why it's harder for Steph Curry to go off for an entire 7 game series when the defense is constantly double-teaming him and forcing somebody else to make a play.*
In the regular season, defenders are more likely to switch or go under and that's partly why Steph is so successful. Steph has worked on his game incredibly hard the past few years, which explains how a skinny shooter out of Davidson has morphed into an MVP. Also if you compare his actual shot chart vs. the rest of the NBA, it's jaw-dropping how far his range extends.
* People knock Steph for not winning Finals MVP last year, but he still scored 26 PPG. Not exactly chopped liver.
