XPoint has only one use case, write-intensive small drives, e.g. filesystem metadata, because of its better latency and durability as compared to NAND flash. It makes no sense as a DRAM replacement or extension, because a) it is tricky to set up and hard to get software that can take advantage of such slower RAM b) at those TB memory sizes, DRAM is of comparable cost. This will probably kill it in year or two as it is unprofitable for Intel. The only way this tech survives is if Intel opens it to the whole ecosystem.
