Obviously this assumes that you can find 4+ extra hours of $50/hr work every month, or you can work 4 hours less. Neither of these assumptions is correct for people who work for a fixed salary.

I think this is the rub the enterprise will be forced to grapple with. Not everyone is going to get $200 worth of value for the organization. In fact since it's not a restricted tool some will waste time and company resources using it. Undoubtedly some will get the value out of it, but it's very likely, that these are the same people providing more than what they're paid already. Nothing has changed other than, potentially, time savings and (hopefully) output improvement. Neither of those are any sort of guarantee though, either. Subjective systems are hard to show value, especially in the long term.

That doesn’t change value. It’s value whether or not you can maintain a profit over it.
