They were numbered in the order that they were "discovered" (or theorized, in the case of population III). Similar to how exoplanets around a particular star are designated "a", "b", "c", etc. in order of discovery, so they usually end up not in any particular order in terms of orbital radii or size. Sometimes letters end up skipped when a letter is assigned and then it's discovered to be a false positive.
So there's logic to it, just not the logic one might prefer.
Is it one of those setups with a glass wedge the partly-open book is placed on with two digital cameras under it to photograph the pages? I've seen those contraptions, they're neat and I'd love to have one for my personal library someday.
Also art AIs would never get hands right.
The thing the headlines keep skipping over in pursuit of outrage-clicks is that this is how you scan books in bulk. The spine is removed and the pages are fed through a high-speed scanner in sequence.
And the books that these companies are scanning this way are not "rare" in the sense of Gutenberg bibles or first-editions of famous works. These are books that have been sitting untouched in libraries or warehouses for decades because nobody wants them and their alternative fate is simply to be pulped and recycled. AI companies aren't interested in quality, they're interested in quantity. It would indeed be nice if they'd release the results of doing these scans to the public, of course, but that's where copyright raises its head to ruin everything. They're just following the law, unfortunately.
I'm all for getting more books scanned and uploaded to Anna's Archive. But that's a separate issue.
Mass and complexity are not equivalent. I doubt that a mountain is more conscious than either.
The Changeling
I think your question is equally poorly defined regardless of where the zero point is placed. Enough for what? What is this threshold for?
There are often things in nature that have natural "division points" along some particular spectrum, where conditions abruptly change (phase changes in chemicals when they pass through transition temperatures, for example) or where you have natural gaps where you don't find many examples because of dynamic feedback effects (the gap between planets and dwarf planets when it comes to their ability to clear their orbital neighborhoods, for example). It's possible that once we can actually measure consciousness and put a number to it we'll find that there are similar gaps, for whatever reason. That would be a very interesting and useful thing to know about. But that's putting the cart before the horse, we don't know how to measure consciousness in a numeric way yet. So any such patterns in the results are purely hypothetical.
If you'd like to go all the way down this rabbit hole there's panpsychism, which posits that consciousness is a continuous scale with "zero" literally being down in the elementary particles. So even a single molecule is not quite zero on the scale, having an extremely minuscule degree of consciousness to it.
I actually kind of like this because it means we don't have to try to put that zero point at some other arbitrary location.
Most of them won't be welcome. They don't send their best.
How in the hell is this not the Onion? I just can't even.
That's a bingo!
I can imagine a couple of reasons.
The most straightforward one actually is "capitalism", but maybe if I explain it a bit you'll accept it? :) I expect that the vast majority of the books that these companies are scanning are bought in bulk from wholesalers at the cheapest possible price, since the goal is quantity over quality. That means they're probably buying the leftover books that the wholesalers are just one short step away from sending off to be recycled into pulp anyway. So re-binding them would mean they're still left with nearly-worthless books that nobody else wanted to buy. It's like those book sales libraries have from time to time, they put out the books that are scheduled for "disposal" in hopes that somebody will pick up a few before they go into the dumpster.
The other reason depends on the physical nature of the book. There's lots of different book binding techniques and not all of them will leave you with something that's easy to put back together. Lots of books are made up of smaller subunits of pages called "signatures", typically 8, 16, or 32 pages, that get stitched together into the finished product. There are coil-bound books, comb-bound books, all sorts of things like that. A lot of them probably wouldn't leave pages that are amenable to a one-size-fits-all rebinding. So that makes things a lot more costly, and again that's a cost that produces a book that's probably worthless for resale anyway.
Honestly I suspect that getting chopped and scanned is the best case scenario for most of the books in this situation. It converts them to digital form, rescuing their contents from being lost. The thing that bugs me is just how these companies squirrel away their hoards of books from the public. And the blame for that lies largely on copyright law, so I can't blame them too much.
