You also have the vacuum of space which is cold but not a long term corrosive nightmare and a conductor like sea water. Also in space you have space so you aren’t going to hit random stuff on the titanic.
This is a significantly more challenging environment.

Would you say the forces are unfathomable?
But let's not forget... our friends in the orbital industry may
only have 1 atm of static pressure differential to handle but they do have to deal with at least 7.5 km/s of orbital kinetic energy (if they ever want to stop being in space). The reentry phase has caused at least 8 deaths I can think of out of only a few hundred people launched. How does that compare to deaths per person-dive below (say) 3000 meters? I'll probably go look that up now...
