I would take with a grain of salt whenever Nvidia (or any company) claims that their technology will destroy . They have a vested interest in saying that and pulling attention towards their brand. Particularly when it's said by a CEO who is serving during the company's highest moment and feels intense pressure to not drop the ball and lower their stock value. He will say outlandish things to try and drive the company value higher, because it's hard to go any higher than where they are now.
Yeah right, let's just hand all patient care, and especially elder care to cheaper, every so gently talking, tender-loving robots. Welcome to the Soylent Green Society.
