CBS Canceling โ€˜Late Show With Stephen Colbertโ€™ After Next Season

I once had a joyful evening in the Ed Sullivan Theater watching magic happen in front of me. An educated, civil, democratic society values the jestersโ€”Stephen Colbert is a master teacher we all learn from.

Apparently CBS Paramount does not, enhancing our decline.

If you are into subsurface microbiology, hydrogen and serpentinization, this is a great read (in my biased opinion) from Dan Colman.

You know whatโ€™s the best thing in the world?
People: your family; your co-workers; your neighbors; those encountered on your travels, etc.
Then, there is fascism, particularly in leadership, that ruins it all.

Not good.

An important, key, element of American democracy passed today; former Senator Alan Simpson of Wyoming.

America, 28 February 2025:

Hey! Welcome to my house.
First, my dog takes a dump on your foot (did not happen).
Then, my partner yells at you.
Next, Iโ€™m going to scream at you.
Last, I throw you out of the house and let you fend for your self.
Good luck.

Adults, please enter the room.

Say goodbye to the machine with indirect costs capped at 15%.
