On the other hand, entrepreneurs and managers are going to want it for their employees (and force it on them) for the above reason.
Of course, such situation is only temporary - if I can suddenly be 10X productive, then so can everyone else, and then the baseline shifts so 10X is the new 1X.
If they have any surplus of money (or loans) they'll try, so those 9 employees may end up becoming team leads or middle management, trying to start new initiatives to get the 10x expansion (and 100x improvement).
The market isn't anywhere near efficient enough to directly translate productivity improvements into labor reductions. Thankfully, because everything that's nice and hopeful and human lives within the market inefficiency; a fully efficient market would be a hell worse than any writer or preacher ever imagined.
The typical work week today is 40 hours. Just like it was 80 years ago. The typical worker is dramatically more productive than 80 years ago yet "doing whatever the fuck I want" time has not increased. Why would it? Employers don't need to pay such that 20 hour work weeks give you the same income. Because everybody around you is ok with working 40 hours.
This won't be different with AI, no matter if the overall effect is 1.1x or 10x or 100x productivity. Because it's not a technological problem but a sociological one.
Those are productivity increases that got our standard of living to where it is. Fewer people doing the same amount of work has, historically speaking, freed people from their current job, allowing them to work on something else.
It's that analogy of the horse, they used to be farm animals. Now, fewer of them are 'employed' but they're much nicer jobs. I'm not sure if the same is true for us this time around though as new jobs being created have increasingly been highly skilled which means the majority can't apply.
Of course in reality in the short term what happens is companies lay off people to increase margins. Times will be tough for workers, and equity keeps gravitating towards those who already had it.
If you remove the effort from those tasks, they will have no value.
10x the value of 0 is 0
Given sane working arrangements or at minimum presence of remote work, it would be a bit shortsighted not to want to get done with your work in a tenth amount of time. In the very least, you're competing for a promotion against less effective people, all while having more time for yourself. If not, you're building labor market skillset in an efficient way so you can hop to a better employer.
I couldn't imagine thinking "I'm gonna do this 0.1x as fast as I could, wasting my life away with pointless extra work, to spite my employer"
The person who realizes that everybody around them is bow at 10X and if they don't follow suit then they will soon be out of a job.
