Pro-Ams – term coined by Charles Leadbeater – are people pursuing amateur activities to professional standards.

Since the industrial age of 18th century, there was a steady rise of professionals and narrow specialization in medicine/science/education/etc.. Amateurism was driven out.

Pro-Am Revolution argues that in 21st century this historic trend is reversing.

Passionate amateurs who have vast knowledge/skills in a certain domain(s), often driven by confusion/lack of sought solutions, come up with new inventions gradually improving their quality, eventually ushering into high-quality products/services.
