Suuuuuper interesting line of reasoning. I think this opens other questions that can help to clarify and better understand where some of the great filters live. We got to space travel and radio communications with the conditions and resources available to us here on Earth. I’ve heard scientists speculate as to whether life could develop on cold worlds in oceans of methane, but never heard about what sorts of technologies could be possible on drastically different planets. Maybe life could develop in a very different way but technologies hitting some real ceilings depending on what’s available. We see even here on Earth, animals with fantastic intelligence such as dolphins that A) never had an evolutionary pressure to develop tool building extremities and B) didn’t have the same access to naturally transformable resources as we did. Understanding where these technological ceilings are based on the resources available on a planet could really inform how many other space capable civilizations are out there. Or at the very least, help us to specify how some of these great filters are arranged.
