DLSS still needs discrete hardware to do that (and keeps requiring new hardware on each generation). Not to mention the types of RAM are not the same and have entirely different tradeoffs - using GDDR for a CPU would tank performance due to an order of magnitude worse latency, using DDR for a GPU would make games a slideshow due to an order of magnitude worse bandwidth. And you'd have to redesign the entire concept of how CPUs and motherboards work to get there, while making AMD and NVIDIA agree to have their chips be behest to the bridges of shitty motherboard and consumer RAM manufacturers even more than they already are.
Integrated systems have come a long way for highly optimized mobile and laptops designs with specific hardware in mind. But even if everything went perfectly - DLSS 5 on a 5090 halves the frame rate and requires a 5090. And it can only do a single style - gritty, high contrast lighting photorealism.
In 10 years will new GPUs primarily be AIPUs? Sure, probably, but they'll still be discrete and they'll still have significant raster and ray tracing pipelines to provide the basis of rendering.
Then again, maybe AGI will come and hardware will fundamentally revolutionize overnight.

I guess I understood "on its way out" to be a shorter timeframe than you intended, sorry!
The technology is very new and currently in its infancy. I do believe it's the future of computer graphics though, where instead of doing "real" photorealistic geometry and lighting, software can render a very simplified scene and have a good enough photo-realistic filter applied to it so that most people wouldn't be able to tell the difference.
Obviously, I believe it'll be flexible enough to do things other than photo-realism in the future.

I think we have different definitions of "discrete" here. In my mind AIPUs are the opposite of discrete. I might be wrong here, but I always interpreted this term as a standalone GPU unit with its own onboard memory — a thing that currently fits into a PCIE slot.
