Because we don’t have AI. We have algorithms putting words after another or pixels next to each other.
Better question is why we don’t use robots with specific algorithms to do those kinds of tasks.
We could if we wanted to. Not necessarily right now, but we’re pretty damn close. If all the damn billions we pour into the data centers putting words and pixels into order went into robotics, we’d have a world where no one had to get their hands dirty or risk an injury at work.
That would also make billionaires billionaires. But that would not stomp the regular folk down, and that’s the catch.
