That are not jobs for the masses for sure :D Some make big, most make nothing.
Nature of things.
But how many jobs create web2? ( the same).
How many jobs create the internet ( the same).
I think the definition of a "job" chances the last 20 years. Its not something doing and repeating.
It is more about doing and repeating and being creative.
So there are not many standard jobs. And the repeat jobs are bot jobs :D
