On the other hand, in your sane world, productivity would be a fraction of what it currently is, for developers and users. You favor computer time over developer time. While computer time can be a proxy for user time, it isn't always as developer time can be used to speed up user time too. A single-minded focus on computer time sounds like a case of throwing out metrics like developer time and user time because they are harder to measure than computer time. In any case, it sounds like a mistake to me.
