I agree with all of this. I was also dissatisfied with how muted his description of long-term vision was.
But then I think back to less "managed" statements from Mark in other interviews, his unbridled enthusiasm for the project, and the fact they're still drilling out the resource, and I'm quietly confident they're making plans in the background for going MUCH larger.
I'll even go so far as to throw out a moral obligation argument. We own a resource (and technology) that can significantly contribute to the green energy transition. We have a moral obligation to use it to contribute as much towards that goal as we possibly can.
(And if it makes us shit tons of money along the way we'll then I guess that's ok too
)
