    There is a future where AI can simply look up the DNA for any individual you specify and it can perfectly reconstruct what they look like, at any age.

      You’re joking, right? There’s a reason genotype and phenotype aren’t synonyms.

          Hadn’t heard of this before but I’m more than a little skeptical, especially if its being used for policing

          "More recently, companies such as Parabon NanoLabs and Identitas have begun offering forensic DNA phenotyping services for U.S. and international law enforcement. However, the science behind the commercial services offered by Parabon NanoLabs has been criticized as it has not been subjected to scrutiny in peer-reviewed scientific publications. It has been suggested that it is not known "whether their ability to estimate a face’s appearance is better than chance, or if it’s an approximation based on what we know about ancestry” -DNA phenotyping wiki

        There’s also a reason identical twins look alike.

          Don’t know why you’re being downvoted, it’s a good point that shows that genetics is the main factor for your appearance

            Maybe but there is more to the outcome than just genes. Certain ones can be activated of deactivated and that can be done by epigentics for example. Gene expression is a thing.

            The AI would need way more information that just DNA to generate an image of the person.

                No, they couldn’t, that’s what’s being said. If you have a huge state machine with billions of parameters, toggling a different subset can yield wildly different results.

                    So? That’s nowhere near the same thing as what you’re suggesting “AI can just take DNA and make the same person”. Look up what twins actually are. They aren’t just DNA injected into some random person.

                  I just re-read their post and yes you’re right, in which case I disagree with them. “Perfect” is not achievable by any means. Maybe accurate enough to be mistaken as a twin for the real person, but not perfect

                Maybe if you mean things like two eyes, two hands, two feet, one nose, but not in any details

            Identical twins also share the same womb, so it’s not 100% genes.

              Same womb, similar growing environment, etc.

              But even then, they’re not perfectly identical. Very similar, but not the exact same.

                I don’t think root comment was saying the AI would generate perfectly accurate images. I think 90% accuracy is doable, just from DNA

                  If you’re just talking about a strand of DNA with no epigenetic info I think 90% is being very optimistic.

      Not unless it can predict all the contributing factors.

      DNA isn’t the full story.

      Maybe they got hit by a car, were a hobbyist boxer, or had surgery, for example.
