Yea, this seems like the initial poster has reading comprehension skill deficiencies and is blaming NVIDIA for lying about a point they never made. NVIDIA is even releasing some of the code they used to power the robot, which further proves that they in no way said the robot was not being operator controlled, just that it was using AI to make it’s movement look more fluid.
I seem to remember multiple posts on large tech websites having the exact same opinion/conclusion/insinuation as the one you originally had, so not necessarily comprehension problem on your part. My opinion: Nvidia's CEO has a problem communicating in good faith. He absolutely knew what he was doing during that little stage show, and it was absolutely designed to mislead people toward the most "AI HYPE, PLEASE BUY GPUs, MY ROBOT NEEDS GPUS TO LIVE" conclusion
