Maximum profit would be achieved by charging the most for the least stuff. And minimizing the cost of that bare minimum. You can do that by eliminating competition so that your prices are the only option. You’d end up with something like feudalism.

But it also depends if you target maximum profits as compared to the population, or maximum profits over all. If maximum profits over all, you’d want to grow the work force as much as possible, maybe colonizing other planets or inhospitable regions of earth.

But maximizing the value of those profits to you requires development to get you more value for less resources. Being a king hundreds of years ago still didn’t get you decent plumbing. So you’d want effecent ways to maximize your pleasure for the lowest cost. Some brain computer interface could be useful there, so that you can create full planets more cheaply.

What happens after all of humanity are enslaved as software devs for the god kings personal virtual reality, I couldn’t guess.
