Why does Lehto say many major discoveries didn't immediately change society?
Because the observations existed but people couldn't or wouldn't connect them to real-world problems; knowledge alone didn't translate into application until frameworks (like germ theory) made the link clear.
What historical example shows knowledge went unused for generations?
Leeuwenhoek's microscopes revealed microorganisms in the 1670s, yet practical public-health changes related to microbes didn’t occur for roughly 183 years until germ theory gained acceptance.
How did germ theory transform human life according to the video?
Once microbes were understood to cause disease, societies implemented sanitation, clean water, and vaccination measures, dramatically raising life expectancy and reducing child mortality.
What does 'macroscopic biomes' or 'fractal universe' mean in this context?
Lehto proposes that life can exist at scales larger than humans—organized, interdependent systems analogous to cells within bodies—so the universe may contain higher-level living structures.
What is meant by 'late gestation' of Earth in the talk?
The term suggests Earth is undergoing a developmental phase toward something new—technological, systemic, or biological—that reframes human activity as part of a larger process rather than an endpoint.
Why are simultaneous inventions and mass sightings significant to Lehto's argument?
They indicate a kind of system-wide readiness or distributed emergence: multiple minds or parts of a system arrive at similar ideas or observations independently, hinting at an underlying connected process.
