SK Hynix Starts Production of 128-Layer 4D NAND, 176-Layer Being Developed
SK Hynix has announced it has finished development of its 128-layer 1 terabit 3D TLC NAND flash. The new memory features the company's charge trap flash (CTF) design, along with the peripheral under cells (PUC) architecture that the company calls '4D' NAND, announced some time ago. The new 128-layer TLC NAND flash devices will ship to interested parties in the second half of this year, and SK Hynix intends to offer products based on the new chips in 2020.
[...] In the first half of next year SK Hynix promises to roll out its UFS 3.1 storage products based on the new 1 Tb devices. The company plans to offer 1 TB UFS 3.1 chips that will consume up to 20% less [power] when compared to similar products that use 512 Gb ICs.
[...] String stacking technology, as well as the multi-stacked design, will enable SK Hynix to keep increasing the number of layers. SK Hynix says that it is currently developing 176-layer 4D NAND flash, but does not disclose when it is expected to become available.

One other thought - I used to be non-plussed by the idea of direct retinal projection, but as my corneas continue to stiffen and medical science continues to waffle about effective solutions for that, the idea starts to hold more and more appeal, and when you consider that the majority of the world's wealth is controlled by presbyopes...

My view is that retinal projection will be the technique of choice for augmented reality glasses.
It would be interesting to see a combination of AR and VR using retinal projection. Flat device, possibly indistinguishable from glasses (still should have two front-facing cameras if possible), and you could manually add an opaque cover to switch from AR to VR mode.
