Your first thought on seeing some of the specs for what will be one of the highest performance computing clusters in the world, is hey, let's invest more in some vaporware from the 00's that never panned out and may not even be theoretically possible. Even ReRAM, which was tagged as a memristor but never proven to be one, had as its greatest promise the possibility of stacking, if anyone could make the process work; 3D NAND and HBM eventually filled that role.
There's still a paper or three a year from labs looking into it just in case, but anything compelling about the idea is long since done.
Sometimes you have to let dead ends die.
