It is possible to have excess productivity. AI allows an existing labour pool to rapidly surpass necessary productivity levels for the existing demand.
IE, let's say I live in a small town and I open a machine shop. Should I hire every mechanic that walks in the door, forever? No, absolutely not; there is an optimal number of mechanics to hire for the demand for services.
If somehow a tool comes to exist that doubles the productivity of mechanics then laying off half the mechanics is next.
If you operate a machine shop in a large urban area, have competitors, and access to much improved low cost tooling, would you:
a) lay off a bunch of workers, or b) lower your prices and capture more orders?
Same thing with accounting firms or marketers or business consultants.

I can say that people are loathe to do it for various reasons.
The article, actually, addresses your claims:
> The optimists will tell you this is just productivity gains. The economy has absorbed automation before; agricultural employment collapsed from ninety percent of the American workforce to two percent and civilization continued. David Autor at MIT has shown that roughly sixty percent of today’s jobs didn’t exist in 1940. New technologies create new categories of work. True. But there’s a difference between an observation about the past and a law of nature, and the optimists consistently confuse the two. The agricultural transition took a hundred and forty years. Carl Benedikt Frey at Oxford has documented that the Industrial Revolution took seventy years before wages and employment recovered for the workers it displaced. In the interim, wages stagnated, the labor share of income collapsed, profits surged, inequality skyrocketed, and the political consequences included the Chartist movement and widespread social upheaval. As Frey puts it: “Most economists will acknowledge that technological progress can cause some adjustment problems in the short run. What is rarely noted is that the short run can be a lifetime.”
So, the author believes that the problem with your reasoning that it will take a long time for the niches you are talking about to be filled (lifetime, maybe more), meanwhile things will look quite bad for most those involved.
I am even less optimistic than the author. The new aspect of this workforce displacement is the centralization. Of course, previous advances in automation also caused a degree of centralization, but AI is posed to become super-centralized if you will. There will be just a handful of suppliers and nobody will be able to challenge them, similar to situation we have with microprocessors today. Needless to say this is absolutely not a healthy situation for the world's economy.
I can’t imagine what claim this sentence is intending to describe.
Obviously individual workers can’t “recover” their wages: 70 years later they’re no longer working.
It also can’t make sense as a recovery of labor in displaced industries, since those are largely gone once they’re supplanted by labor-saving technology.
We've seen rapid growth of knowledge work at the same time as increased productivity, and there doesn't seem to be any compelling reason that greater productivity will reverse this persistent trend.
ok, so machine shops aren't really central to the argument, but the collapse of demand is.
The most productive places in the world are also those with the highest incomes and wealth generation. "Excess productivity" is either temporary or a sector-specific phenomenon, it doesn't apply to society as a whole.
> “Most economists will acknowledge that technological progress can cause some adjustment problems in the short run. What is rarely noted is that the short run can be a lifetime.”
The redundant professionals will need to find other ways of generating wealth from their productivity, and that may not be possible in a reasonable amount of time. Not in the scope of their remaining lifetime.
