Or all 15 people are still employed doing the work of 22.5. Or even more people have been hired now that each person can generate 50% more value than they previously could. Or people are reallocated from the AI assisted task to another. Or some combination thereof.
I had thought about this and this is an accounting issue. It's not always the case that if one worker can build one meter of rail per hour, then with a thousand workers we can finish one kilometer of rail in an hour. Maybe more efficiency is not needed and we need to produce a cheaper product, so we make layoffs.
