You're right, we don't "need" most modern conveniences. But they save us time and provide an improved quality of life. Why do we need power tools? Why motors? Why electricity, running water, artificial light? I joke, but AI is one of a long chain of tools designed to save us time, or extend our capabilities and reach. Why are you particularly opposed to this one over others? I return to my argument: AI is concerning because of its potential for change. I don't think we can prevent it from existing, but we can make it accessible to normal people and not solely the domain of the rich.
