It sounds like you don't really have 15 years experience. You have a few years experience that you've been repeating over the last 15 years. You also tend to sound more like a scripter than a programmer (not that there's anything wrong with that!). Becoming a fully fledged programmer would therefore be the next step for you, and you could certainly take it, but I doubt you will. You are lacking one or more of these:
* confidence
* direction
* motivation
Learning ability is not likely to be the issue, it's the lack of desire to learn that is at the root.
Find something you are really passionate about and make that happen using whatever tools are considered the best in that domain. Many older programmers unwind and expand by writing games or personal projects that scratch their itch. Find something that interests you and get coding.
Personally, I'm working on a pair of games right now. One with a team (8-16 month duration), and one that will take the next few years of my life which I am starting work on solo. They give me reason to fire up the compilers, read the docs and flex my chops.
