Where Have the Writers Gone?

A weird fact I found out not long ago:  most of my old writing buddies haven't published much in years.  I hadn't been paying attention, but one day I was looking up my PT Dilloway books on Amazon to see if I had any reviews and just for the hell of it I clicked a link on an old issue of Indie Writers Monthly from 2013.  Check this out:

• Andrew Leon doesn't have a book listed since February 2018 and that was nonfiction.  The last fiction book was April 2016.
• Briane Pagel doesn't have a book listed since November 2016
• Rusty Carl (aka Rusty Webb) doesn't have a book listed since September 2013
• Sandra Ulbrich Almazan has a couple of short stories over the last couple of years but nothing novel-length since October 2017
• Nigel Mitchell doesn't have a book listed since June 2018
• Neil Vogler doesn't have a book listed since April 2016
• Amazon says Jay Noel has released two books this year but I think they're both re-releases from a few years ago
• Even Tony Laplume hasn't published any fiction on Amazon since June 2018

The exceptions are that my buddy Al Sirois just published a novel last month, I guess Michael Offutt finally published the conclusion to his trilogy last October, and Cindy Borgne co-authored a book this January, which I have on my Kindle but I haven't been reading much during the pandemic.

It's kind of depressing that it seems like most of my former writing friends have mostly stopped writing--unless they're using different names.  What could be behind this?  Maybe they're just busy with families and jobs and stuff.  If any of them want to give me a shout out, go right ahead in the comments.
