It doesn't see "straw" or "berry". It sees a vector which happens to represent the word strawberry and is translated from and to English on the way in and out. It never sees the letters, 'strawberry' is represented by a number, or group of numbers. Try to count the Rs in "21009873628" - you can't.
This is exactly my prove my with Facebook and the thing that's making it downright close to unusable now -- the crap that you see that nobody intended to share. My feed is a literally endless stream of awful memes because someone I went to high school with ten years ago tagged their friend in a comment and now I have to see that.
I want something that shows only what my friends explicitly posted, in chronological order, and without a tiny character limit.
