What the does that have to do with what OP said? OP, correctly, pointed out that we don't detect the lack of O2, we detect a buildup of CO2 (because it causes respiratory acidosis). If the CO2 is removed, there's nothing to cause the panic response, the situation itself notwithstanding. It's still nea that it works with an impaired amygdala, though.
first of all - the co2 isn't removed ...

Iirc they did tests where people agreed to blink a certain number of times etc.
Strange, they never asked those condemned to actually utter some sound or mimic something, isn't it? Well, that's because residual muscle twitch is not controlled and is not conscious. Rapid drop of blood pressure renders the person (well, their head, in that case) unconscious within a couple seconds and it is downhill from there.
And because making sounds without lungs attached to your throat is kinda hard
The outcome everyone knew would happen. I don't understand the desire to go to that depth to see a sunken ship when I presume there is camera footage of it available. You can't get out and do anything, your view is probably pretty crappy given the thickness of any see through material. I see the allure with Everest and the view for your 60 seconds at the top must be impressive and it is a physical feat. But a sunken…
The desire is motivated 100% by bragging rights for the uber rich. So they can recant their journey as an intrepid explorer (/s) at a cocktail party with their other smug uber rich friends. Same for going to space.
Maybe, just maybe, the ultra rich have similar motivations as most other people and want to see cool shit. They just have way more spending money to make whatever they want a reality.

In that scenario, as long as they could keep CO2 levels down, running out of oxygen isn't so bad (ignoring the other troubles). The human body can't detect a lack of oxygen, you just get tired and light headed and pass out.
> The human body can't detect a lack of oxygen Unless you know you are trapped and running out of oxygen.

It's waste the same way insurance* is waste. The difference between something certified and something not is exactly this instance, when the uncertified thing fails unexpectedly. The rest of the time, the difference is a "waste". Insurance is a waste until the accident happens and you get value from insurance. *the general concept insurance, not the disaster that is US health insurance.
> Insurance is a waste until the accident happens and you get value from insurance. I can't quite put my finger on it but there is something dubious about "insurance" or at least as it currently exists.
* Asymmetry of information. The insurance company has all the data on the statistics, costs etc.
* Insurance companies very happily take your money, but when it's their turn to do the thing you literally paid them for, they look for every possible reason to weasel out.
