That's a great point. But I want to add that anecdotally users do care about performance and they will often thank you for anything that is noticeable. Sometimes just because it feels nice, but it can also enable a fast feedback loop, which increases immersion and productivity. In a broader sense, we use computers not only because they can perform work autonomously but also because they are fast, correct and remember details almost perfectly.
