How long can you survive in a 4000 psi water pressure, going suddenly from atmospheric pressure?

In and of itself, what is actually incorrect about that statement?
I think a lot of normal people are going to smugly harp on that statement, but in and of itself it seems perfectly reasonable to believe that there's a diminishing return to safety measures for anything at some point.
The issue with this sub thing seems to be that they made some really bad choices, including apparently having glass that wasn't rated for the actual depth they were going to, choosing a gaming controller that apparently had a history of wireless issues, and other dumb issues with the design of the sub.

Do airplanes count?
As Futurama famously said, airplanes are rated for a pressure differential somewhere between zero and 0.7 atmospheres. With the positive pressure being inside the plane. This submersible needed to survive a differential of ~350 atmospheres. With the positive pressure being outside the craft.

this "scoffing at safety and regulation" shit being seen as "hip, cool and rebellious" and somehow a desirable trait is actually completely fucking bonkers to me. Careful analysis and engineering to make things as safe as possible and well characterized is incredibly rewarding and satisfying.

Yes, who cares if someone killed a child and several other adults by repeatedly ignoring warnings of clear dangers! Why shouldn't people be allowed to experiment with negligence at the cost of human life?

Somewhere a redditor did the math and I believe it would have taken 24ms for the glass to break and the water to rush in. Instant death if it was indeed the glass.
Just how instant is that death? Do you die from quickly drowning in the water or is the water pressure enough to also crush your skull quick enough to make sure you die without having the chance to feel anything? Guillotined people can still be alive and feel about 30 second safter their head has been removed from their body.
I reckon its instant death. If the sub imploded or the carbon fibre hull failed, then it means large amounts of debris come rushing to you very quickly.
I don't think there will be any bodies to recover.

I think it’s one thing to build your own insanely dangerous exploration device and try it out yourself but to try to make money by selling people tickets for rides on it is far beyond mere “experimenting”. There’s also the very substantial public cost of rescuing the victims of these short-sighted ”experiments”.

Just thinking about that outcome yesterday caused my blood pressure to skyrocket. Dark, cold, cramped, fetid, hungry, thirsty, knowing oxygen is running out.
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.
Yes, but as you hinted at the human body can detect a rise in CO2 levels and it doesn't take much for things to start getting really uncomfortable and fast. To your point, if you could somehow manage the CO2 levels then you would just peacefully fall asleep and die.

#78No idea why every single journalist kept forcing the "air remaining" theme. It was far more likely that the sub suffered a catastrophic implosion at the time contact was lost. Glad to see it confirmed, and finally people stop posting the nonsense about air. Shame about the passengers though.
I think at that point regardless of the actual issue, it ceases to be a rescue operation.
It did feel weird to see countdown timers, at least it felt gross to me.

He killed several people and was credibly accused of making misleading safety claims to customers.
Regs are written in the blood of misguided libertarians and their unwitting victims.
It might be more acceptable if the government (taxpayers) didn’t inevitably pick up the tab for bailing out their recklessness.
