It's a bit ironic that knowledge work will become obsolete before blue collar work. I disagree with the author that it will become completely obsolete in the next 20 years (although certainly in the next 200), but it will change significantly and there will be a massive downward pressure on knowledge worker compensation as the barriers to entry have been decimated. On the other hand, good luck getting your AI to unclog your sink, remodel your kitchen or fix your AC any time soon.
