btw, Thomas Edison didn't invent the lightbulb. Lightbulbs were around. He improved on it. Actually, his lab assistants did most of the work. And speaking of necessity is the mother of all inventions, Thomas Edison's phonograph invention (again, it was his lab assistants) came before he applied it to a need. It took him a while to figure out to apply it to the music industry.

Thanks for listening. I debated using the TE example beforehand, I am ashamed to say that I gave that speech knowing he wasn't the real inventor. I needed to connect to my audience, this was in another country and TE is one of the few inventors on their knowing.
