There was never a slowness in the apps I've worked on that came down to requiring memoization in React versus other basic things like doing pagination or other ways of rendering only things that would be displayed at the time for the user.

Well, yes, those are alternate ways to deal performance problems, but they are not necessarily any easier than adding a bit of memoization.

No those solutions (and problems) were completely tangent to adding memoization. My point is that I've never seen a performance issue where non-memoization was the problem.
