A non sentient artificial intelligence is a tool. A sentient artificial intelligence is a person or something similar.
We treat tools differently than people.
It's fine to buy a tool or break a tool
It's not fine to buy a person or break a person.
Now, sentient AI doesn't exist, but it is the stated goal of companies developing new AI.
The moral considerations for the ways in which AI companies make money when AI is a tool is different than if AI ever becomes sentient.
It would be wrong for AI companies to sell the use of a sentient AI without compensating the AI since that's slavery. The profit incentive would drive them to keep selling AI use regardless, though.
Problems of capitalism and our broader social system come into play then. Who makes this technology becomes very important.
Personally, I dont trust AI companies to be good parents, and that is what they would be if they made a sentient AI.
The methods of raising an AI are wildly different from raising a child. But the companies would still be making plenty of choices that influence how the AI turns out.
