[pedantic-fool]

You're a software developer, so learning is something you're doing constantly without even noticing.

Sure the youngsters have an advantage in sheer symbol ingestion power, but you have experience and probably some intuition as to how to work with information, knowledge and systems thinking which they won't have. Just be open to new tools that go with the territory.

My concern in your case would be the ability to find relevant employment afterwards, as it is somewhat rare to change field mid-career. Certainly that, depends on both the job market you'd be targeting, and your willingness to take an "entry-level" job.

And if all else fails, you still have your developer skills to fall back on.
