  • Yeah, it certainly can go that way unfortunately. I’m in favour of digitisation generally, but at a minimum it relies on:

    1. Redundant storage (always), hosted and paid for by the government (in this case).
    2. Published and documented open file formats.

    I believe that, in general, things lost to time on the net violate one of those two rules. They either resided on a single privately held server which was discontinued, or the data was locked up in some proprietary file format which was inevitably replaced for the sake of selling the new software product.

    The benefits of pulling this off correctly are enormous:

    1. Data lasts a very long time.
    2. Documents can be authenticated and change-controlled.
    3. Documents can be shared with any number of users simultaneously.









  • I have no idea how these work, but one hack idea off the cuff:

    You get the light for free. At least when your lids are open; that’s how vision works. A cheap digital watch lasts ages on a tiny coin cell because the polarisation of the LCD, which passes or blocks polarised light, takes minimal energy. Stack up a passive polariser, and the active LCD-like layer, (and maybe a second passive layer?) and you can cast selective shadows on the retina.

    This gives you monochrome “smart vision” in the same sense as a monochrome Casio wristwatch. No idea how to tackle issues of focus at such a short focal length, or achieving any sort of active display let alone colour.

    Maybe the whole thing is a pipe dream crackpot idea.
