A 1% probability of "ruin" i.e. total extinction (which you cite is your assessment) would still be more than enough to warrant complete pausing for a lengthy period of time.

There seems to be a basic misunderstanding of expected utility calculations here where people are equating the weighting on an outcome with a simple probability x cost of outcome e.g. if there is a 1% chance of the 8 billion dying the "cost" of that is not 80 million lives (as someone further down this thread computes).

Normally the way you'd think about this (if you want to do math to stuff like this) is to think about what you'd pay to avoid that... (read more)

Just came across this post from a friend.  I'm a co-founder of Life Itself which would count itself as part of the ecosystem and we have been developing an ecosystem mapping of this space over the 2y+ and published an online guide and directory in 2021:

https://ecosystem.lifeitself.us

We specifically sought to try and identify some of the key features and settled on "paradigmatic, integrated and engaged":

This project maps an emerging ecosystem centred on a radical, alternative approach to social change – one that is simultaneously paradigmatic, integrated and engaged. Discover key features and ideas of this growing space. Explore associated organizations, individuals and initiatives. See how it relates to other established and emerging movements.
