I frankly would not buy anything on the promise of future proofing or an upgrade path, because as Intel has proven several times, upgrade paths are a lie. Buy what you want now for the performance you can buy today, and treat anything else like a bonus. AM4 is an aberration, I believe, not where the industry as a whole is going. I think AMD needed AM4 to be largely backwards compatible so they could make the value argument for people who had bad memories of the FX era, and now that they're more competitive they don't need to be as pro-consumer.
