Really, you agree with the masked "Anopheles"? It looks to me like we don't understand why or how energy, creation, and Kardashev money works, if we can't see around our own long-conditioned and encouraged instincts of personal greed.
If we never get it, it will be because the greed of a few overcame the needs of many, and just because we made that choice doesn't mean other intelligent species made that choice too.
In fact we should question the intelligence of making such a choice.
Musk is no exception, his greed is very obvious, and very worshiped.
We need a few influencers to be saying this, to offset the obvious greed-closed-mind influencers like Musk.
The universe looks a very different place, if we can see that extinction of humanity is a choice, a choice to honor and worship greed.
The irony is that the greedy can't see around their greed, to see how nature actually works, to eliminate greed.
