Musk gives 'fart' reply as ex-Meta Chief AI Scientist calls his 'flying' car 'crappy'

Yann LeCun, Meta's former Chief AI Scientist, hit out at Musk, calling his 'flying' Tesla Roadster "crappy specific impulse". "Even assuming...50% of the car's mass is compressed air, that just gives...less than 10 seconds of useful thrust," LeCun said, adding, "Cute demo, but totally impractical. But of course, you knew that." Musk replied, saying, "I fart in your general direction."
