  • Fear the forest?!

    I don’t agree that humans feared the forest for most of our history. Cite the evidence Mr. Nelson.

    Challenge claims made with no evidence Chris.

    I think ancient humans understood and navigated nature superbly well with minimal fears.

  • Extra positive

    You should learn about the genetic bottleneck phenomenon, quite easy to drive extinct. We are deliver actual WWE backbreakers to life everyday. Cheetah’s would be done in short order if they dropped to 0.3%. The Cheetah’s niche may get refilled over time.

    Great positivity for nature’s resilience, but animals and plants are actually quite fragile. We’ve destroyed most of it in not very long compared to the scales you like consider.

    Stay positive, but try to empathize or walk-a-mile in the shoes ... more

  • Very Guest Dependent

    So while I’m giving it three stars, it’s more like a middle point between 5 and 2. James Krellenstein’s episodes are amazing, for example, but many episodes can fall into nuclear advocacy traps, such as excessive hippie punching. Hence, this is a series which can be great, but is very uneven.

Talking Points

Recent interactions between the hosts and their guests.

Megaprojects: Some Assembly Required w/ Ian MacGregor
Q: What was the biggest surprise during the project?
The scale and integration of 7,000 pieces of equipment into 1,400 modules, plus the need to engineer while constructing—never finishing the engineering upfront
Fission Impossible? Financing New Nuclear w/ Michael Seely
Q: What changes did Sizewell C bring to the financing approach compared to Hinkley Point C?
Sizewell C uses a regulated asset base structure, allowing early charges to customers and a government-backed framework, reducing the need for the heavy construction risk borne solely by the operator and enabling broader private and public investment under a government-supported risk framework.
Fission Impossible? Financing New Nuclear w/ Michael Seely
Q: What are some of the main financing models used in Europe for nuclear projects?
Models range from government-backed sovereign or utility debt with guarantees to more market-based schemes like contracts-for-difference and, in the UK, regulated asset bases that allow charging customers during construction to de-risk private investment.
Fission Impossible? Financing New Nuclear w/ Michael Seely
Q: Why are nuclear plants challenging from a financing perspective?
Because they face two big risks—construction risk and long-term revenue (offtake) risk—and the cost of capital is highly sensitive to these risks, with long build times and delayed revenues rapidly inflating the total cost unless de-risked by guarantees or backstops.
Limits to Growth of LLMs w/ David Helmer
Q: What do you think is driving the AI hype cycle, and is AGI likely any time soon?
The hype largely stems from clever marketing and the perception of rapid progress, but the fundamental limits show up in safety, reliability, and costs. AGI as an imminent, universally transformative breakthrough is unlikely; progress will continue, but with substantial caveats and the need for guardrails.
