This part is very interesting. "Even now my voice is reaching millions"

Chaplin knew this message was for future generations. When he says "even now" it means, hey im long dead but this message is finally being herd around the world.

Chaplin & Nikola Tesla were friends. Tesla told Chaplin what was to come down the line like the internet, what he called "the transmission of intelligence" I honestly wouldn't be surprised if Tesla himself didn't write this speech.

"The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of the planter — for the future. His duty is to lay the foundation for those who are to come, and point the way." - Nikola Tesla
