Study cited by @emollick

Brief

@emollick highlights a study showing a flood of AI-generated books is crowding out human authors: No-AI books earn less per title than in 2023 in 7 of 8 genres, with only Fantasy/horror up +35%. Tuhin Chakrabarty calculates the catalog grew 38× over three years while quarterly revenue rose only 9×, lowering average earnings per book (post published 2026-07-28).

Why it matters

Study cited by @emollick: No-AI books earn less per book than in 2023 in 7 of 8 genres; the only genre where human authors improved is Fantasy/horror (+35%).

Key details

  • Tuhin Chakrabarty (@TuhinChakr) reports the books catalog grew 38× cumulatively over three years while quarterly revenue grew only 9×, so average revenue per book has fallen as many more books compete for a barely larger pie.
  • Post published 2026-07-28 by @emollick highlighting the study and Tuhin Chakrabarty's imbalance analysis.
Source evidence

Really interesting study. There is, as everyone expected, a flood of AI books. And it is crowding out human authors: "No-AI books, on their own, earn less per book than they did in 2023 in 7 of 8 genres. The one genre where human authors are doing better (+35%) is Fantasy/horror"

Here's the imbalance at the heart of the paper. Over 3 years, the books catalog grew 38x cumulatively. The book's revenue? Only 9x quarterly. Way more books fighting over a pie that barely grew which means the average book earns less than it used to. (4/n)
