This one time I was at school and I had a terrible stomachache. Perhaps I had digested some bad food. So I did what any intelligent student would do, and I stopped into the bathroom.
I had to search for a clean toilet. I don’t know why public toilets in private buildings ever become gross, but it happens nonetheless. So I found a satisfactory toilet, and relieved myself of the pressures of my meal. When done, I’m about to flush the toilet, but there’s no lever. Or button. Or any type of trigger for flushing. Just an infrared light. Which would not be triggered.
I hate leaving things messy, especially when I had to seek out cleanliness myself. But I didn’t have a choice in this situation.
That’s when I realized, that machines would be the end of us - not because of artificial intelligence but because of unintelligent human design.
