First, we have to agree on what a plot hole is.

My definition of a plot hole in a story is something that simply can not happen given the existing rules of the story, or something which could only happen in an unexplained and if not literally impossible than at least so unlikely it is practically impossible way that defies everything else we know about the story.

This would be an item inexplicably jumping locations, a character having knowledge they could not possibly have, or a character or item being in two places at once. Things like that which gnarl the story.

What it isn’t: A character making a bad decision, a character acting unusual (even to the point of acting out of character- that can be bad writing, but not a plot hole), a character forgetting something, a plot contrivance, an unlikely coincidence, something being unrealistic but consistent within the context of the story.

I commonly see poorly written scenes, or scenes where someone thinks a character was acting irrationally, or scientific or legal or other plot points that are intentionally written to serve the story described as plot holes.

With that description, I’d say quite a great number of works of fiction don’t have plot holes.

downtime

minimal retraining

I feel your pain. Many good ideas that cause this are rejected. I have had ideas requiring one big downtime chunk rejected even though it reduces short but constant downtimes and mathematically the fix will pay for itself in a month easily.

Then the minimal retraining is frustrating when work environments and coworkers still pretend computers are some crazy device they’ve never seen before.
