Throughout our human existence there are those contributors to advancement of society, not accepting of status quo and take the initiative to drive change! Then there are those that can't see the forest through the trees, pooh-pooh any visionary ideas for advancement, the fuddy-duddy naysayers, afraid of change and/or just simply happy to sponge off the "status quo" society in which they live.
In 100 years, we are likely to remember the name of Elon Musk as one of those visionary change agents that built on the great men and women who came before him -- such as Henry Ford and Nikola Tesla.
When Nikola Tesla invented AC, those naysayers where there! Even Nikola's own mentor (Thomas Edison) was blinded by his own DC invention...and couldn't accept what Nikola's AC "revision" was to become the future solution to power our cities!
When Henry Ford vision was to bring the automobile to the masses, travel was limited as there were no network of fueling stations and limited horsepower...and of course those naysayers where there!
So...let the naysayers crawl back under their rocks.
History will ultimately prevail!
