paper details - title - Limits to Economic Growth - author - Thomas W. Murphy Jr. - date - 21 July, 2022 - publication - Nature Physics, comment, online - https://doi.org/10.1038/s41567-022-01652-6

summary - Physicist Thomas W. Murphy employs reductio ab adsurdium logic to prove the fallacy of the assumptions of his argument - In this case, the argument is that we can indefinitely continue to sustain economic growth at rates that have held steady at about 2-3% per annum since the early 1900s. - Using both idealistic and simplified energy and waste heat calculations of energy and waste heat compounding at 2-3% per annum (or 10x per century), Murphy shows the absurd conclusions of continuing these current trends of energy and waste heat emissions on a global scale. - The implications are that physics and thermodynamics will naturally constrain us to plateau to a steady state economy in which the majority of economic activity needs to not depend on physically intensive

summary - This book provides rationale for why capitalism won't scale renewable energy, but a public sector government approach might - What about the alternative of community-owned or cooperative-owned energy infrastructure? A pipe dream? - Is renewable energy just not profitable and therefore has to be subsidized? - Perhaps it could be seen as a stopgap to buy us time until fusion, deep geothermal or other viable, scalable options become widespread?

answer - Planet Critical podcast - Terrence Deacon - We're in existential crisis - but difficult to convey to most people - why? - Our symbolic abilities have given us tremendous capacities - Over the past two thousand years, - our ability to communicate - has allowed us to create amazing technologies - Example: James Web telescope - millions of hours of human thought - thousands of people collaborating - now we an look back billions of years - We are no longer isolated minds - Our symbolic capacity allows us to - share thoughts, - collectively plan futures - unlike any other species

I've seen people describing how many cards they think they need before the method is useful, but this is the first time I've seen someone use a timeframe to describe useful effects.

Niklas Luhmann indicates that it may take a number of years to reach critical mass. This may be different for everyone based on the number of ideas they place into it and the amount of work they do in creating connections.

Ward Cunningham, the creator of the wiki, has indicated that he thinks it takes roughly 500 pages in a wiki for the value to begin emerging.†

How many notes and what level of links/complexity is a good minimal threshold for one to be able to see interesting and useful results?
