He tried so much to look funny but it didn't look good on him. And at one point he said 4090 is like taking home an equivalent of a $10,000 PC, and he expected the crowd to clap, but no one, literally no one, clapped. Because everyone knows GeForce prices have been monopoly prices for years and 4090 is intentionally crippled by nvidia drivers to be less capable than it really is (see George Hotz in-depth analysis).
To me it seemed like he tried to justify its price as if it were a small part of a $10k setup with lots of RGB lighting but for some reason mainly for watching movies. No one has one just for watching movies, and it's likely more than the rest of the gaming PC build combined. Monitor possibly included.
Someone should tell Mr. Huang that it's not 20 years ago and that their products now cost 2x the amount of all other components in that "pc entertainment system control center" combined. He seems to not know, out-of-touch billionaire as he is.
