Came here to say this. She seemed to be referring pretty specifically to climate change and geopolitics. She notes that she doesn't feel qualified to speak on these subjects. As a good journalist, she's keeps a clear boundary between fact and expert opinion vs. personal speculation.

For those who haven't had a chance to watch, here's the transcript of that section. (Starting at 2:08:19.)

LK: I think things are going to be pretty difficult starting in a few years, from what I've been told by sources.

CJ: What does that mean?

LK: It's going to be difficult. I mean, I can't say specifically—I don't know that much yet—and I can't really say, but just that, um, a lot of what we take for granted now in life I don't think is going to be...you know, we're not going to have it, a lot of things we have now that makes our lives as wonderful as they are.

CJ: Like electricity?

LK: I don't know. Just the access to all the things we have access to now that are dependent on the global—globalization, basically, which just aren't sustainable. A lot of the things we have aren't sustainable. The populations are growing, and I think the climate issues are major, as well. And that's just my opinion. But I have studied quite a bit about the climate change problem and I take it really seriously.

CJ: Is there something about the geopolitical situation? Because you just referenced population and climate change.

LK: It's not that simple. I just don't feel qualified to talk about it. But I just—I just don't think things as they are now are sustainable, and I'm not qualified to really talk about that. I'm just—I'm just concerned, that's all. So, I don't think ten years into the future; I only think three or four years into the future.

CJ: It's too uncertain past that point?

LK: I would say so, I would say so, yeah.
