Well honestly the tech can be developed the only really tricky part would be developing a software that can recognize which signals to send by themselves and which ones it would have to duplicate cuz if you honestly think about it to be able to achieve a full dive your motor functions would be intercepted while the signals to your heart and lungs would have to be duplicated and let pass through the peace of equipment that transfers the signals to keep your body IRL alive so the calibration would have to start a few minutes after the signal collection begins… Not to mention creating a device that can even pick up the signals without having to be implanted in the body but that said I’ve been trying to figure out a way to come up wit some way to make this a reality of my own…
