If you could rewrite any book’s ending, which one would you choose?
If I could rewrite the ending of any book, I would choose Yuval Noah Harari’s 21 Lessons for the 21st Century. I deeply enjoyed the book, though I’m nowhere near 0.00001% of Harari’s writing ability.
Still, I would end it on a more hopeful note. AI is here, and there is no going back—it’s a one-way ticket. Instead of ending with uncertainty, I would add a 22nd chapter about how people can adapt: how to learn new skills, stay employable, and reinvent themselves whenever technology changes.
In programming terms, it would be an infinite loop: Learn → Adapt → Work → Relearn → Adapt again. That, I believe, is the real lesson for the 21st century.
