TED-Ed: Is there a limit to technological progress? - Clement Vidal

The video explores the potential limits of technological progress, introducing the Kardashev scale, which classifies civilizations based on energy consumption, and Barrow's scale, which classifies them by the size of objects they control. It discusses the potential for human civilization to advance along both scales, harnessing both stellar energy and subatomic technologies. The video also considers the implications for detecting intelligent life in the universe, such as finding a Dyson sphere around a distant star.

What are the three levels of civilizations according to Kardashev's scale?

How does a Type II civilization utilize energy differently than a Type I civilization?

What is the significance of the Planck length in the context of technological advancement?

In what ways could advancements in energy efficiency impact civilization's future?

What implications do the observations of super dense celestial bodies have for the search for intelligent life?
