I watched the whole damn thing because it was super interesting. Wrote a paper back in college about how to design architecture around memristors to get the great performance for both technical (AI, machine learning) and gaming applications. The ability to quickly access logical address space as part of the same physical hardware as your "CPU" opens up computing ability to absurdities such as no need for RAM. Sony appears to be marching down this architectural path. It's a bridge (pun intended). The stepping stone. The transition to "all if it is one hardware wafer constructed into interconnected lattices." Memristors appear to have never taken off for multiple reasons related to physics (I am guessing). But there will definitely be something along the way to help merge the hardware CPU and Memory into one "piece" and give us that very very delicious instant memory availability - eliminating the data communication gap.
