The way this manifests isn’t mass layoffs after an AI is implemented, it’s fewer people being hired at any given scale because you can go further with fewer people.
Companies making billions in revenue with under 10k employees, some under 5k or even under 1k.
This is absorbed by there being more and more opportunities because the cost of starting a new company and getting revenue decreases too as labor productivity increases.
Jobs that would otherwise exist get replaced. Jobs at companies that otherwise wouldn’t exist get created.
And in the long run until it’s just unprofitable to employ humans (when the max their productivity is worth relative to AI falls below a living wage), humans will continue working side by side with AGI as even relatively unproductive workers (compared to AI) will still be net productive.
