So, I understand that because water is not compressible, animals without air in their bodies are safe at such high pressures in the deep sea, but what I'm wondering is what would it look like if a human in the deep sea was suddenly exposed to those pressures, as would happen if a submarine rapidly pressurizes? I know the lungs would collapse and whatnot because the air would be pressurized into I'm guessing a liquid, like how propane sloshes when under pressure in a tank, but what else? What causes the instant death? Maybe the water shoots into nose/mouth so fast it acts like a bullet and applies a bunch of force to the walls internally?

These are styrofoam cups that've been crushed by the pressure at the bottom of the ocean. The water isn't looking for your nose, it'd just crush your outsides into your insides until you hit a relative density, like the cup, but not as pretty. The air in your lungs would instantly compress and heat to several thousand degrees C, turning your insides back into your outsides. I think.

Holy shit and all of that happens within 2 nanoseconds I think? So that's why the victims in that submarine wouldn't even know it already happened because our brain takes 4 nanoseconds before we could process that pain.

The velocity of a catastrophic implosion like that would exceed Mach 2 (686 m/s). Nerve conduction is about 50-60 m/s. Dead before they knew anything was going wrong.
