Lots of jobs like daycare, teachers, cleaning, the material costs are near zero and your ability to increase productivity using technology is very low.

You can reduce quality of cleaning. But it's very hard to clean faster and better at the same time.

These industries are not going to be optimized by an AI. The only optimization is lower overhead or lower salaries.

Sure, we could have robots in daycare, but I don't think lack of AI is why my wife would have concerns :)

Of course there's jobs that don't have a productivity boost from AI. The question is whether across the entire economy there will be a 5% GDP boost.

Teachers, cleaners, and daycare workers may see 0% gains, but don't be surprised if that is made up for by 10% gains the productivity of tech, law, marketing, advertising, manufacturing, government, etc. (okay maybe not government).
