I too know a guy who did TEDx talk. After he did this talk, he suddenly became self-proclaimed intellectual authority on everything from Quantum Mechanics to politics to religion to what not, on his Facebook page.
He couldn't write a 3 line Python program or solve a high school trigonometry problem or answer a basic history question.
