I think this is where the new technology comes in. There is demand for 10x (or 1000x) the memory that we're using at the moment, so someone/something will satisfy that demand. We haven't had that demand up until now, because 16Gb was a perfectly reasonable amount of memory that could run pretty much anything, and if that won't then 32Gb will. There was zero demand for 16Tb memory machines because no-one had any application for that much memory. Now that's changing, and there is demand for that much, so we'd expect to see that being made available.

But the existing tech we're using for 16Gb probably isn't going to scale to 16Tb at a reasonable price point. And the price point is relatively inelastic - people are used to paying <$5K for their computers, and they're not going to go much above that. You'll get early adopters paying $10K or more for a machine that large, but not the early majority. And even then, obviously, $10K is not going to buy you a 16Tb memory machine.

So there's room for a new technology to come in, where there wasn't previously. This is what happened all through the 90's, and we churned through a bunch of standards and technologies to try and keep up with demand.
