    What's the main blocker (other than the current inflated cost) for using HBM instead of DRAM as the primary memory for consumer electronics?

      HBM isn't dramatically better in every dimension. You get huge bandwidth and good energy efficiency per bit transferred, but not necessarily a meaningful latency improvement and capacity expansion becomes tied to the package
