Employees didn't care about that though, as they could get another cheap hired hand to do your work went you went kaput. Plus it didn't take much clarity or muscle to do most factory, farm etc work, just tedious persistence -- so you could be overtired all the time and they would still get productive work out of you.
With mental work it's not so simple (e.g. there are bigger costs in training you and in employee churn).
despite being a genius i just couldn't do skool. Eventually i concluded that the topics just bored me. It just now struck me that they bored me because i barely slept before school. in the weekends i would sleep 14 hours then did things mentally that blew my own mind. to borrow an example from the discussion: i could look at a chessboard and explore openings without moving a piece, all the way to the end game then the next variation. there was this huge inconsistency with my one ear in other ear out school performance.
I've always felt there was a dramatic difference in my mental performance/IQ/genius-level thinking when I got a full 9 hours of sleep versus just 7-8 hours. Very noticeable in school or the early years of work.
Imagine we forged a formula for 1000+ year projects. They would require more money periodically and the availability of new funds would have a strong influance on the value of previous cash injections. One could buy the "failing" project cheap then simply do the new cash injection yourself OR in case of success one could obtain the shares for less than their value.
We have so many papper driven games like this already. I see no reason why this one wouldnt work.
You might be interested in the wonderful book series "The Three-Body Problem" by Liu Cixin. It explores (among countless other things) how huge expensive projects that last multiple generations could be implemented.
A great what-if. While not exactly the same, I think you could look at the publicly funded projects like the Euro-projects, NASA, or the Soviet space program that still yield results.
Now imagine the big public companies doing the same.
