AI is likely to be the biggest beneficiary of this architecture. The on-memory processing chips are likely to be simpler than the CPU ones (i.e. more akin to GPU cores), and allows parallelism- both of which point to numerical processing and AI.
I like the idea of flipping DIMMs to get capacity and processing improvements, and also the thought that mass-produced memory with this tech could potentially significantly reduce the cost of AI hardware through commoditization
