>>same life support tech
No it isn't. Orion's life support tech has to work in zero g.
>>main difference is one resists 14.7psi differential from inside, the other resists a 16,000 psi differential from the outside
Aren't we forgetting that orion has to bear intense vibrations on top of rocket, go supersonic on the way up, have equipment that works in ZERO GODDAMN G, be able to dock with other spacecraft with out destroying them, work all while be bombarded by deadly space radiation and micrometeoroids, keep four humans alive for 21.1 days in space, survive hypersonic reentry on the way down, deploy chutes to slow down, and deploy airbags. And if anything goes wrong anywhere, there's a good chance said humans will be very dead.

All James Cameron's sub has to do is meet pressure vessel code and carry enough breathable oxygen for ~ 2 days, go down, and go up. If anything goes wrong, he can drop the ballast and be at the surface pretty quickly.
