Cause and effect... is life because of the balance between nitrogen and phosphorous, or is the balance between nitrogen and phosphorous because of life?
Is there a reason this wasn’t posted on the supporter rss feed for podcast apps?
I think there is also a possibility of a Great Filter to robot super intelligence. Maybe we cant make the AI we all fear, or maybe if its possible its unfeasible for it to colonize the galaxy for some reason. One thing our meat computers can do well is run on very little energy, maybe meaningful non biological intelligence is just too power hungry ..
Perhaps DNA coded carbon based life is the endpoint of the search for more efficient AI.
Fraser, ask your favorite AI to Sset up a regular schedule with Craig to get together at least once a year. Subject TBA.
Great interview 😊😊
This interview was amazing! I had a lot of fun listening to it while at work :D
A brilliant interview, worthy of 10 years subscription.
i understand we have not found earth like worlds because the planets we find are around red giants because younger stars are too bright to find a small planet like earth in the light, we can only find giant planets further out from bright young stars. the red giants have likely destroyed their earth like planets in the habitable zone.
Very interesting interview Fraser; I particularly enjoyed the fermi paradox and AI discussion! Thanks also for nudging (pushing?) me in Patreon's direction!
Terrific interview. Thanks~
One of your best … covers a lot of ground!
Fraser, your AI views are ridiculous. Large language models are a bad joke. They are not intelligent and you should know better.
Large Language Models happen to be good for language tasks, not surprising, and coding is a language task. That's what Fraser is talking about. The LLM coding scene has changed significantly due to Claude Code, and that's very recent.
What a great interview and conversation! Love the bonus questions too.
