I think what many people don't get is that the post-scarcity economy is coming, one way or the other.
Point in case: I do web development in an agency, and while my work isn't always all-out pointless like that of some of my peers who produce power-point presentations (no joke - they produce presentations for a living - we make quite an amount of money of this), I also see clearly that most of my work comes from LAMP and WordPress being so shitty that building something that resembles a useful model often requires hours of custom programming per project. I work part-time, 5 hours/day, so I don't go insane and even that remaining work is mostly a classic "bullshit-job".
We are moving into an all out cyberpunk post-scarcity economy - that's a plain and simple fact. Meanwhile the luxury problems I have come from cellphone manufacturers artificially inflating phone-storage prices or not offering the exact type of phone I'm looking for, the girls I meet often being to tied up in social media to be useful for quality time and me being to lazy to book my surfing vacation for late summer.
Money in it's current for is either becoming worhless (negative interest) or being removed alltogether (sharing economy, access culture).
The problems that await us will stem from people and societies who can't deal with a post-scarcity economy and turn fanatic - religiously, politically or otherwise. That is the problem Jack Ma is probably talking about.
Other than that I personally see no problem with the rise of robots.
If we play our cards right, we can have an utopia in a century. But probably the nutbags are going to screw this up again, using religion and/or totalitarianism, as usual.
