Yep I bought into the hype and had dreams about its use in all sorts of devices. I saw it as saving energy when devices went idle. Smaller DRAM backed up by loads of 3D XPoint. And maybe we would get in-store type databases. The sky opened up. And then it just gradually got nowhere and the sky clouded over again. I never did have much hope in Intel after Micron gave up.
