Crazy how fast the landscape in the world of PC gaming changes. This was exactly the sentiment for 16gb of ram, not even 6 or 7 years ago. I built a mid range PC ~2016 (Ryzen 7 1700, RX 480, etc) and everyone seemed to agree that 16gb was future proof for the next decade. 

Fortunately I don’t play the latest AAA games on my PC, but it’s remarkable how fast that “future-proof” 16gb ram was made totally obsolete. (Not to mention clock speeds.)

I’m not sure there’s really such a thing as “future-proof” in the current state that tech is in. Especially when many new products seemed to have stagnated in terms of innovation, companies are leaning heavily into creating an artificial “ladder” (ie. Apple, Nvidia) for product differentiation, which is then furthered by soft locking the newest features to the most recent products.

I don't think 16GB is obsolete now. I think it has simply moved into the "not future proof" category. Still very workable. But maybe not the best value for a new build? If youve had 16GB for 6 years though, I think it's hard to argue it wasn't the best value for you at the time, especially as it will probably still serve you well for the next 2 years or so. But I know what you mean, the industry moves fast. Sometimes I wonder if I'll always be on PC or if I'll eventually convert to console? Never...maybe....well never say never haha
