You touched on this in your article, but the effects of robotics and automation on jobs is going to be quite disruptive in the next few decades. Robotics/automation advancements will result in job displacement as well as forced specialization of labor (a new industrial revolution, in some ways).

If UBI isn't implemented before this, we could have large scale resource management issues and societal upheaval (riots, etc).

There are other ways to secure capital for UBI, such as taxing companies that utilize robotics. However, if we take that taxation route, we could remove incentive for companies to pursue robotics work in a country, which could allow other countries to get the competitive advantage.

Lots of interesting thoughts here.
