I think that might be a chatgpt specific thing, I tried with bing in precise mode and it responded with this:
“A sow is an adult female pig and piglets are baby pigs. Pigs have four feet, so a sow with six piglets would have a total of 28 feet (4 feet for the sow + 6 piglets * 4 feet each). Is that what you were asking?”
Why does an AI have to be sentient to be intelligent?
