"As far as you know"? Well, what do you know? Or what do you think you know?
These boards will last until AMD adopt DDR5 on the mainstream desktop, so that's 2021 at the earliest. That's 2 generations of CPU before it would need to be replaced. But then look at the specs of these boards, look at the specs of the Ryzen 3000 series (and what that means for Ryzen 4000 next year), there's nothing more you could add to make it any more "future proof" than it already is, and X570 systems will last for donkey's years.
