But if I say "I object to AI because <list of harms> and its water use", why would you assume that I don't also object to alfalfa farming in Arizona?

Similarly, if I say "I object to the genocide in Gaza", would you assume that I don't also object to the Uyghur genocide?

This is nothing but whataboutism.

People are allowed to talk about the bad things AI does without adding a 3-page disclaimer explaining that they understand all the other bad things happening in the world at the same time.
