In the second video you'll notice there's been an edit, where he goes from describing the useless class to the solution of taxing AI and using the money to help people. My guess is they cut out the part where he discusses the fact that there will be no point in retraining anyone if AI does everything.

If you are a horse in the year 1900 you'll be very useful, but by 1920 most of your job has been replaced by cars and tractors. If at that point the horse really can't find a new job, then the cost of it being alive (food, healthcare, living space) will be compared to the market value of horse meat.

Lucky for us there is no market for human meat, but 8 billion people (and growing) worth of carbon pollution, food, living space, healthcare, entertainment, voting rights, property rights, risk of revolution compared to the value of them not being there... Until very recently in human history, the solution has always been to "fire" them.
