That was what I was wondering about when I bought my Macbook Pro in 2015 - but I'm still using it. I have to run 2 VMs plus Xcode before the RAM becomes a noticeable problem, and even then it's perfectly usable in practice. (Switching between VMs is not instant, but the very fast SSD means I'm not waiting for too long.) I think a quad core CPU would be a much more useful upgrade than more RAM. And come to think of it, it was also what I was wondering when I bought my desktop PC in 2012, and I'm still using that, too. I'm not saying it's unreasonable or foolish to be concerned - far from it, given that the RAM can't be upgraded - but I still do wonder when the tipping point for this will actually be reached in practice. During my formative years, you were doing well to get 3 years out of a PC, and now here I am with a laptop that's that old, figuring it will last at least a couple more years...
