In One Lifetime

In Carl Sagan’s essay “In Praise of Science and Technology,” which appears as chapter 4 of his book Broca’s Brain (see location 682 of the Kindle edition), he writes:

There are many people alive today who were born before the first airplane and have lived to see Viking land on Mars, and Pioneer 10, the first interstellar spacecraft, be ejected from the solar system.

Sagan wrote that essay in the 1970s. This got me thinking about my daughter, born in 2015. She will almost certainly live to see the year 2100. What marvels will she have witnessed by that time? It sure is a good time to be alive.
