gregorumAn actual book stores more data than that and for longer. At that point, why not just etch the data onto a metal plate or something? 8K is only a few pages of text at 12pt. It could easily fit onto two sides of a small-ish metal plate, etched in 8pt or so, and it would last, potentially, for millennia.
I think the idea is to improve upon this tech so the capacity would become larger.
It’s FRAM, which has been around for ages. The problem is its prohibitive cost— hence the 8k.
