Good post.

Yeah over the past year I've become convinced that humans' limited working memory is actually a superpower, because it allows us to avoid this type of problem.

Isn't it less that we avoid the problem of limited working memory & more that we are constantly confronted by it and so we have had to devise processes for quickly organizing data by relevance to immediate & long-term goals, forgetting information that is no longer relevant, and creating new working memory chunks?
