I get a lot of mail from people who agree with me, but are impatient and want to propose methods of moving to a better situation very quickly – with some kind of Ponzi scheme that people would buy into quickly, thereby causing things to change rapidly. I always respond to these people that what I’m actually advocating is a slower and more deliberative process. I’d rather take 20 or 30 years, because that’s probably how long we have before the employment crisis from automation will become severe. What I prefer to advocate is not that we change as fast as possible, but to engage in a more deliberative political and longer-term dialogue, which is why I wrote a book rather than proposing a Ponzi scheme to spark a quick transition. Besides, our current arrangements might not give rise to lock-in because ultimately it’s not sustainable.
