Potatoes aren't fruits, they're really soft rocks.

They're the same family, if you let a potato plant flower and bear fruits it'll have little cherry tomatoes looking fruits. Haven't tried eating that though. And it's harder to grow from seeds

Since potatoes are mainly long chain carbs, they are actually not a fruit but a cereal/grain.

In this case I meant it as writing without thinking. An AI bot would probably output something without much substance, but also without the grammatical error.
