 So the optimism that everyone should have comes from the fact that we have the technology to solve this problem today. You know, wind and solar are incredibly cheap energy sources. You know, solar is the cheapest energy that humanity's ever had. We can switch and largely, not completely, but largely phase out fossil fuels today. We're not doing it because of the politics of the problem and how powerful fossil fuels are as a special interest. You know, so I just want everyone listening to understand this is not a technical or a scientific problem. It's a political problem.
