The author confuses money for wealth when they are two very different things. Look at the teleporting chef example - if food production could be done so efficiently that only a few chefs around the world were needed, then social wealth has increased. There would be a massive pool of surplus labour that the now redundant chefs could put to use elsewhere.

As others have noted, the newly redundant chefs would be out of work temporarily and if that is the only skill they had, then they would be at a disadvantage relative to everyone else. Yet that disadvantage would be many more times offset by the benefit us non-chefs would accrue (from cheaper meals for example) and still allow the redundant chefs to do something else.

That's the nature of capitalism - creative destruction. The process is beneficial collectively, but some individuals benefit or loose more than others. And that's why (most) countries provide some sort of redistribution mechanism to smooth out those individual inequalities. The solution to any dehumanizing effects of the capitalist system is not to limit the market's ability to drive innovation and efficiency, but rather to ensure everyone enjoys those benefits more equality.
