One must always behave with respect to the dead, and to dependents when someone dies suddenly. I'm sorry for your loss.
That said, I think the lesson here is complacency--I can grab a tank turn on put a little air in the bc and stick the reg in my mouth and jump in and be almost certain that I will survive. To try that with any rebreather...
I can't help thinking that this is more likely to happen the more automated the system.

I had the germ of a thought the other day: I was talking on my cell phone, and I lost the call, tried again and the battery went dead. Compare the cost and level of complexity of a cell phone to an eCCR. Yes I know there are numerous flaws in the analysis--for example the cell phone is not engineered to be a piece of 5 sigma life support equipement, but it is a multi Billion dollar market that has been optimized by a lot of talented people, and it still screws up. Now one could come back with "the space program argument", but I don't have that much money to spend. I don't even have the money to buy something like a Mk 15x.
My conclusion with admittedly no direct experience--I just bought a orca which will be turned into a mCCR. If I could I would probably get a MK15--But the level of training and "carefulness" required in maintenance and predive procedures might outweigh the robustness of the system when diving.
Which brings up another point: To a certain extent risk sports in general and rebreather diving in particular require you to know yourself. Are you are a panic prone dumb ass or a cool under fire rocket scientist. Are you the sort of person who can do the maintenance to letter of the law every time or somebody who just "dives in". Self analysis is hard but your life hangs in the truth.
