Given commercial pressures would a Boeing reentry vehicle be over designed to such a extent that on such a failure (failure to separate, entering with the wrong attitude ?correct term?) result in "...the craft righted itself before the escape hatch was burned through"?

I would assume it would work the same as with the soyuz, provided that the service module separates/explodes before the capsule reentering the wrong way is irrecoverably damaged. Basically, all space capsules have their of gravity placed in such a way that they will automatically orient themselves heat shield forward once they encounter the atmosphere. So once the service module is gone, it should flip into the corre…

I think who you're replying to is implying the escape hatch would have been cheaper if it wouldn't last long enough before burn through during improper re-entry

Makes me wonder why put all this effort to make space-travel safe for crews. Why not focus on remotely controlled or AI autonomous vehicles instead?

Buzzwords doesn't make something more reliable/less error prone. You really think that by throwing in something like AI, which can fail in unexpected ways, be a good idea?

I think it's worth studying and developing further, for instance study how to make AI which will not "fail in unexpected ways"

I think we already do — there have been roughly 15 satellites etc. launched for every human who has ever reached earth orbit over the entire history of human spaceflight.

Good. I was just wondering why this project in particular needed to have a live crew.

It’s hard enough to get an AI to work well in a known situation line driving, never mind an unknown planet. But more importantly - where is the fun in that?

You are right some people find it fun to go to dangerous places, I assume. Think about the crew of StarTrek and of course Buzz Lightyear. Personally I would rather send someone else to space than go there myself :-)
