The all laughted at Edison. I'm watching and can't wait to see the results. Someone someday will come up with Warp Drive. How bout you?
Nobody laughed at Edison. He invented stuff. Proved it would work. Patented it. Then announced it and got funding.
They laughed at Tesla, Edison's apprentice. Now Edison's stuff is obsolete, except the light bulb. Tesla's stuff is still in use around the world... Tesla, father of Alternating Current...
Edison offered Tesla $50,000 to come to the US and work with him. A huge sum of money back then. When Tesla got here (not easy for him), Edison told him, "What, you believed that"? Edison insisted on DC power which was unworkable, Tesla's AC power has been used ever since. Kudos to Elon Musk for naming the car after him.
