I don’t even want AI to replace us, but it’s a great tool with many use cases.
There might be a way for us to adopt AI as a tool without bringing ruin to many people, but I don't believe that is the goal of anyone building AI.
As it stands, I don't believe there is anything ethical about AI in it's current form. So from that perspective, I vehemently deny there is any value in it
At one point in history, people like you were asking why anyone could be anti-slavery. After all, it was impossible to deny the economic value of slaves.
