And the passenger compartment appears to be spherical, which is basically the perfect shape for external pressure (like an compression arch is for vertical loads), so the only weakness will be the compartment material itself or more likely any joints or and penetration points.

Going deep underwater has similarities to going into deep space. We would like to send humans to Mars, for example, because we believe they could make more discoveries over a shorter time than robot cars that have to wait as much as an hour for a command from Earth to reach them.

No matter how deep we go under water, however, the signal delay will be negligible. A craft with arms could be operated by someone on shipboard who would have a better view from a camera signal shipside as someone looking out a porthole inside the underwater craft.

The only reason to put a human so far down is for human interest which might increase funding and TV revenues
