He was able to tinker with a radio at age of 10, in 1940. I had my first electronic at 19, in 2003, growing up in India. Today, almost anyone in the world can have access to the latest tech easily. Great minds were there and are everywhere in the world, they just didn't have access to resources. Think how fast the research monopoly of US is going to shrink.
Growing up in a Third-World country, I was tinkering with electronics at age 10 and built my first crystal radio at age 11 from junk parts. Dumpster-diving isn't hard as long as you don't mind the occasional dead dog.
Whereas I would expect that in the 3rd world by the time you got your fingers on it it must have been technically beyond salvage.
Crystal radios are neat!
