I have no idea if this is practical but I remember when flash memory was this suspicious semi-science fiction thing too. There are probably some people on this site that remember the same for DRAM. There have been loads of things in between that didn't make it. Some of them were semi-crackpot, some actually went into production like bubble memory and Optane. Few of them have met the sweet spot of the market in a way that let them move from a niche to a dominant form of memory, but still I wouldn't discount that it's possible to invent a new form of memory that will take over the world!
