CXL is coming, which will allow attaching ram from beyond the box. That will be exciting.
It won't have 64 channels of ram bandwidth (8cores x 8channels) but it will also be much much more obtainable (once it starts showing up in volume, stops being totally exotic). If you have a couple dozen TB of data you want to be pretty fast, could be a huge win.
There's also switched versions, with multi-host. So multiple hosts might share a ram drive (atm this would be partitioned up, but I've dreamt of clustering fs like HAMMERFS for multiple decades & am not gonna give up the dream yet!).
And perhaps maybe the on-ram filtering might eventually work & be good, so ram could perhaps do push-down filtering on its own, for scanning through tables!
