Chris Claremont is leaving Uncanny X-Men

As the years pass, you wear out the machine of the soul
People say: "He must be put on the shelf,
He's written himself out, it's high time"
There's less and less love, less and less daring
And time is crashing into my forehead
Then time comes for the most terrible of amortizations -
That of the heart and of the soul

Mayakovsky
