The product exists because there is an ill-defined unmet demand. At this point the product is an equipment solution for a skills limitation, but so was the BCD when it was introduced. At some point the electronics, programming, and hardware will become smart and reliable enough to be useful. I am skeptical that this particular product will prove to be a breakthrough development though, but I wish them luck.
For example, auto-inflating and controlling ascent with loss of consciousness, set to end a dive at a NDL or low gas limit, or tied into a decompression procedure in a no-overhead environment. Obviously a quick override option is required.
Short of a counterlung like on rebreathers, a key component of our buoyancy control is our breathing management in concert with lead and a BC. Unless this thing is constantly wasting gas with every breath trying to compensate for changing displacement, I don’t see this iteration being well accepted by the newly trained divers. There is an acceptance problem anytime a device produces unanticipated results, which usually results in a crash of confidence.
