They are talking about using to to cure cancer for starters. As far as NVDA goes one case use of their chip is the omniverse. Where you can for example, build a factory in VR and test every system, and component as if it were real. So you can back test. And make everything more efficient and spot problems. If you don't know what AI will do maybe you should try using google a little more.
I use AI almost everyday. If you want to build a house give the deminesions and window and door holes and you will know to the exact piece of wood how many boards you need to frame it. I used it to put solar in my camper. Instead of figuring it out I asked Chat GPT a few simpl.e questions to figure out charge rates and draw downs and saved a lot of time.
I want to plant my land in Florida. You can google plants but AI can compare them assess rain conditions soil types etc. It plans trips very well. People even use it to post replies to ignorant people online saving valuable time.
For example I could ask Chat GPT why AI is more than a glorified google search and your comment would look extremely silly.
If you can't make use of AI in the very near future you will not have a future. AI is useful for people that strive to be productive.
