Cosmos: Possible Worlds

I started watching "Cosmos: Possible Worlds" on Disney+ tonight. It's very
good. I didn't watch the earlier Neil deGrasse Tyson series (Cosmos: A
Spacetime Odyssey), but that didn't hamper my enjoyment of the episode. 

The wonder of science and emphasis of argriculture as "the mother of all
revolutions" lines it up with "Sapiens", the fantastic history of humanity
by Yuval Noah Harari.

At the end of this episode, he projects a future in which humans launch
LOTS of TINY little spacecraft, akin to the light dandelion seeds that blow
in the wind. These spacecraft will travel at 20% of the speed of light, and
send back data from the stars and planets we've sent it to explore. It's an
absorbing vision of the future!

Postscript: Close Call with COVID

I have not developed any COVID symptoms!
