Nearly nobody is arguing against using AI for personal fun.
People are arguing against AI destroying entire career segments without providing benefit to society, especially to those displaced. People are arguing against how it so easily misleads people, especially when used as a learning aid. People are arguing against the enormous resource usage.
But in terms of power/emissions, data centers are far far better. The waste of potable water could be addressed if we make them, but the inefficiency of running locally cannot be.
I still prefer to run locally anyways, because fuck the kind of people who are trying to sell AI, but it is absolutely more inherently wasteful
My father in law told me how a guy at work created several pictures with AI for decorating the floor, bragging about saving costs since he didn't use licensed pictures. But the AI may have used licensed pictures to learn creating those images. Artists lose money due to this being done by companies, which could very well afford paying the artists.
I guess a private person creating memes with AI is not threatening anyone to lose their job.
