To be fair, competition and investors tend to pressure corporations to place profit above any other values - the only way to maintain those values is to be forced by an external, 'arbitrary' force, like the law, or eccentric owner unconcerned with pure profit.

An external, accountable force like the law can work but not a truly arbitrary one like heirs not subject to any constraints.

But they are subject to constraints! They're subject to the law (ideally, anyway...), so the two options aren't in opposition. So yes, it can't work reliably, but still better than the pure profit motive, which is guaranteed to forsake any other values.

Do you know any projects that try to solve this problem?

Government regulation solved parts of it - stuff like environmental protections or labor laws. But in general, it's a very hard problem, and I don't think a theoretical solution exists yet. You can read more about it here: https://slatestarcodex.com/2014/07/30/meditations-on-moloch/

Hundreds of years later, company loses site of its mission, descendant of the great one (second coming) appears and steers company back to greatness.

Kind of a strange fantastical vision out of the fiction category. Not something I'd expect the would-be CEO of a public company to seriously suggest.

Honestly, it's kind of insulting to himself. If I had as many delusions of grandeur as he does, I'd assume I'd instill the company from birth with such unwavering great culture, that it'd never go astray even 300 years in the future.

It seems like he’s pretty confidant he’ll be able to instill unwavering values in his family though.

I wonder which of those is more likely, but they both seem pretty fantastical.

I don't think beings will even be "walking" into "rooms" to "say" stuff in 300 years.

do you think we will have ascended to pure energy or all be dead?

asking for a friend.

Likely those chosen ones shall ascend to the fourth plane of existence, leaving all others to suffer in the third. Just like in NG+.

Like the ancients, huh?
