Re: AI?
The one thing that humans have a hard limit to is time. This affects how much information they can consume, or in your case how much music and how many videos its physically possible to listen to or watch in one lifetime. Even a super fast computer will take a noticeable amount of time to write to 32GBytes of memory.
I can see a use for very high performance GPUs in gaming environments where you're creating detailed worlds in real time (and where the detail glitches for the most part will go unnoticed). LLMs are useful but when I played around with them I found that they generated material which either took a long time to consume (read) or took me a relatively long time to utilize. (I don't get involved in Marketing so generating reams of BS in real time isn't something I need to do -- everything I do has to be verified and checked.)
The history of performance oriented computing has been for the most part applications soaking up surplus computing power, often with meaningless, if pretty, visual effects on graphical desktops. (For those without state of the art hardware its just a mess -- nothing works properly so its a constant fight to get anything done.) Adding more power is useful to sell more computer but I doubt if it will increase the quality of work, it will be just adding yet more monkeys and typewriters.
