You're mis-describing the situation.

Who is building AI? Giant tech companies, which are owned by extremely wealthy people. It is their wishes that matter, because they literally give the orders. "Whoever pays the piper calls the tune."

Giant tech companies spend a lot of their money paying for salaries and gig developers. They wish they could spend less money on those things, because then a much larger share of their revenue could be profit.

Teaching AI to write is an obvious step toward not having to pay humans.

Nobody said "I want to be dependent on AI." What they are saying, what they have been saying, shouting at the top of their lungs every single day for decades, is "I hate paying my employees, I hate having to pay them a fair wage, I hate having to pay for their benefits, I hate having to hire additional people to manage all the employees I hate paying, and I hate that wielding all my power requires me to persuade and negotiate with these humans instead of simply dictating."

They will not stop until they reach the ideal workforce size: 1 employee, who they can just give orders to, and then that employee does the "gruntwork" of wielding huge technology to accomplish the mission.
