Sure, with far less human labor. That's my point.
> That road system directly and indirectly created millions of jobs.
Yes. That's my point. It created millions of service/intellectual jobs. Or are you saying the highway system created more jobs for those who own shovels?
If people moved from physical to intellectual labor in the past century. What will people move into if intellectual work is mostly done by AI. Assuming that the AI the evangelicals promise comes to fruition.
