I considered writing a long carefully constructed argument laying out the harms and limitations of AI, but instead I wrote about being a hater. Only humans can be haters.
I Am An AI Hater
I am an AI hater. This is considered rude, but I do not care, because I am a hater.

“But I am a hater, which is a kind of integrity. It means I am willing to disagree with anyone, even if it is rude.”

After WWII the world called it the last war. It wasn't. Just 3 years later was Deir Yassin massacre. And we are 30 years after signing Dayton and finishing war in Bosnia.
And the world still learnt nothing.
