The Subplot Thickens

I admit I've been hesitant to continue writing. It's not so much writer's block since most of the creative work has been finished.

I'd been inching along the 2nd edit until I had come to a place where I looked at the page and I didn't know what to do. And I've finally figured out why.

My rushed first draft of the next book contains far too many subplots. Even with my notes I find it difficult to keep track of it all.

One of the biggest subplots revolves around a computer program which becomes self-aware. I thought it was a good idea at the time, and that I could bring something new to the concept. Now I'm not so sure. The old "rogue AI" idea has been done to death.

The payoff for this subplot came in several turning points in the story. But looking back, it comes off as feeling like a cheap "get out of jail free card". I'm considering dropping the whole idea, which means re-writing at least several thousand words, not to mention finding new ways to move the plot along without this thematic device. It might all fall apart.

There are certain passages of writing about this rogue AI which I am very proud of, but I'm hoping the book will be better off with these massive cuts.

Has anyone else looked back on their early drafts and felt the sting of regret when seeing a wonderful part of your work that needs the chop? Did it work out in the end?
I remain hopeful!
