I love the sound of a dive computer HUD - though I'd be curious to see how it would be affected if your mask leaks. I guess the 'watch' would still be present - probably a good idea as masks can get lost (I had mine accidentally kicked off by a fellow diver once).
I do take issue with your assertion that certifications can be cast asunder. A lot of what's learnt is about safe diving (e.g. don't dive after you fly, safer dive profiles, what to expect at different depths wrt buoyancy changes, dci, getting narced, etc.) and what to do when technology fails.
Wetsuit buoyancy has a due to neoprene is pretty handy if you surface and are in distress. If you're towing an unconscious diver, for example, and are only relying on their bcd to keep them afloat their legs drag terribly (as is the case for dry suits) and it makes the rescue very very difficult. There are other safety advantages too - it's not clear to me why getting rid of buoyancy is a great idea.
