The results were, as you've probably guessed, disappointing. DALL-E surfaced standard-issue arms and hands. Midjourney showed veiny, muscular arms with hands that seemed painfully clasped together, but still, the anatomy was standard-issue. Thumbs, too, were inescapable. I tried again several times, rewording the prompts and making them more specific, all to no avail. If I was gonna make my arms happen, it certainly wasn't going to come easily.
It's easy to point to a technical reason for this experience. Bodies like mine are incredibly uncommon, and the probability that anyone who looks like me found their way into the AIs' training data is very unlikely, let alone in a well-described, well-classified way. I am the spotless giraffe.
