Unless the Boeing CEO and their children fly back down in the Starliner along with the astronauts, I don’t think anyone else should risk their lives on it.
Sorry I don't provide any sources, but in ancient Rome the engineer that built a stone arc sometimes stood right below it when they removed the scaffolding supporting it. If he did a good job - he lives.
That one was the exception to the rule. The vast majority of CEOs aren't actually that dumb and reckless with their own lives, just greedy and sociopathic.
Those spaceships weren't as obviously stupid as OceanGate's sub. Also, those two aren't typical CEOs either, they're a bit more like OceanGate's CEO: they're ones who built their company from the ground up, and have some kind of strong drive to be the next Howard Hughes or something and be a leader in some revolutionary thing (spacecraft in their case, submarines in OceanGate's).
Boeing's CEO is not like these men. He's just a typical CEO who didn't build the company, and is just a temporary hired gun really, like most of them.
Let's take a moment to appreciate the stupidity. Of course it's not nice to be a cpt. Hindsight. But he tried to build a sub in a... Sub-optimal shape (non-spherical), used inappropriate tools (wireless PS controllers? Wireless? Really?) and the most important idiotic mistake, after all these somewhat accepted mistakes - HE DIDN'T TEST IT. From what I read he just wasn't into testing.
It baffles me the level of stupidity a human can reach with no consequences from the society, what so ever. He is just a small example! I don't have enough space to write here all the CURRENT people who are literally running the world and are being proud to be stupid in public. How stupidity became a commodity?
Maybe it always was. But smartphones and social media definitely pushed it a lot.
You can even see it here, whenever people get downvoted just for posting something that is too uncomfortable (e.g. bcs it's criticism that touches their own lifestyle, ...).
There are ripple effects everywhere. Nowadays it's like yoi said: People are often explicitly proud to be stupid.
