Mankind+Womankind+Everybody. You. Me. Everyone reading this. Then your a human being. Or a computer. Which is closer and closer every day. All hail the AI overlord.
Not to be confused with a "decent human being" or a "horrible human being" which are something else entirely.
Its never to early to sell out human being(s) for a pat on the head.
That guy on social media seems less and less like a human being every day.
