I read it too, and I feel like Musk's predictions are spot on. In the next few years, the development of AI and robots can indeed meet all of humanity's material needs, and humans might actually live well without working. However, AI and robots can't solve the emotional value of humans, because human emotions are constantly accumulating and diverging. No matter what is provided to make you happy, you'll eventually get 'bored.' In the end, only drugs can solve your emotional problems, but drug usage also follows a divergent curve, and ultimately, you'll just overdose and die!
