I would like to share with you this awesomely concise video created by CGP Grey on the subject of automatisation, and on some aspects of fourth industrial revolution driven by AI:

In many areas where automatisation brings highest returns,computers and machines are already considerably outperforming people. This tendency of incremental substitution of human labor was most evident in industry and manufacturing, but besides this incremental advancement of machines in industry, a new wave of transformational changes can be expected from AI.

Why Explore Space?
In 1970, a Zambia-based nun named Sister Mary Jucunda wrote to Dr. Ernst Stuhlinger, then-associate director of science at NASA’s Marshall Space Flight Center, in response to his ongoing research into a piloted mission to Mars. Specifically, she asked how he could suggest spending billions of dollars on such a project at a time when so many children were starving on Earth.
Stuhlinger soon sent the following letter of explanation to Sister Jucunda, along with a copy of “Earthrise,” the iconic photograph of Earth taken in 1968 by astronaut William Anders, from the Moon (also embedded in the transcript). His thoughtful reply was later published by NASA, and titled, “Why Explore Space?”
