Citation needed. My experience with people outside the tech bubble is that they don’t know what RAM is, and will not consider it when purchasing a computer. Most of these people now also live primarily on a phone or tablet too, because their computers are too slow.
This is a perfect analogy. To stretch it, the majority of sports car owners are developers. The vast majority of your users are not.
