I am confused by this comment. You said "RAM" (contrast to "DRAM" in the article title) but I think you are talking about DRAM sticks? But those have not gone away (other than with some laptops where it's soldered on and not upgradable).
Going from 8MB to 32MB in the 90s is still comparable to going from 8GB to 32GB today.
One difference is just that the price isn't dropping at the same rate anymore [1], so it doesn't make as much sense to buy small and re-buy next year when bigger chips are cheaper (they won't be much cheaper).
Another is that DRAM speed is at the top of an S-curve [2], so there's not that same increase in speed year-over-year, though arguably the early 2000's were when speeds most dramatically increased.
