It won't be me or you. Whoever it is, they will not share any of the economic upsides of AI with the public unless they are legally forced -- zero, zip, zilch, nada. Even then, they will keep the lion's share for themselves, and they will use their surplus to shape society to their advantage.

So yes, many millions of us have a big problem to worry about, especially considering how much struggling there already is now.
