Ignoring the obvious math problem here, I think the broader scope is important. Some of the point from preceding comments is that overall longterm output is not changing. So if somebody is oneshotting a week of work in an hour, but has the same annual output... where are you losing all the normal productivity that should have happened the rest of the week/year?

If one week of work can be reduced to an hour, then you should be able to complete a year's worth of work in 50 hours. If you break that into two 25-hour weeks (because a 40x dev earns the right to loaf?), what is that dev doing for the other 50 weeks in the year? What is making them so incredibly unproductive 50 out of 52 weeks in a year?
