De-centralized computing is similar to what happened in IBM/Sony Cell CPU: independent SRAMs with an associated vector unit, doing transfers to the main/host DRAM via DMA using a high performance ring buffer. The benefit is simpler architecture, but more difficult software implementation, although for AI or graphics development behind an abstraction could be perfectly fine.

Well, Cell was a module on a CPU SoC much like a mini-GPU or DSP. It did not perform the way Sony and IBM hoped because it could not get the bandwidth to the RAM to keep it busy. Computer in RAM is something different.
