Here is a very good discussion by Nelson Schwartz, here is one excerpt:
He is not predicting an imminent resurgence. Like most academic economists, Mr. Cowen focuses on the next quarter-century rather than the next quarter. But new technologies like artificial intelligence and online education, increased domestic energy production and slowing growth in the cost of health care have prompted Mr. Cowen to reappraise the country’s prospects.
“It’s better than it looked,” Mr. Cowen said. “Technological progress comes in batches and it’s just a little more rapid than it looked two years ago.” His next book, “Average Is Over: Powering America Beyond the Age of the Great Stagnation,” is due out in September.
The link is added by me, and the article covers other individuals too. There is also this:
“The great stagnation will end for a lot of people but not everyone,” Mr. Cowen said. “I think there will be great breakthroughs but the distribution of those gains will go to owners of capital and intellectual property.”
