That's not a particularly good scientific hypothesis (since it isn't testable except in hindsight), but it's still a fun speculation to ponder :)
This means that things get weird if you pose the following hypothesis:
The title of this stream then comes from noticing the parallels between those changes in the speed of communication within and between organisms, and considering how the development of human society has impacted the speed of information and material transfer between different parts of the world, to the point where dysfunctions in human social mechanisms can now have a clearly measurable impact on the planet as a whole (e.g. acid rain, coral bleaching, the ozone hole, anthropogenic climate change)
However, the possible aspect of the Gaia hypothesis that most fascinates me is comparing it to biological evolution and in particular changes in the speed of information transfer within and between organisms.
In particular, we can consider:
The "Gaia hypothesis" is an interesting notion that broadly entails conceiving of a planet and its biome as an aggregated entity: https://en.wikipedia.org/wiki/Gaia_hypothesis
Evidence to date suggests that the Gaia hypothesis isn't particularly useful for understanding the historical evolution of life on Earth.
