If your industry truely is going in the direction where there's no paid work for you to code (which is unlikely in my opinion), nobody is stopping you. It's easier than ever, you have decades of personal computing at your fingertips.
Most people with a thing they love do it as a hobby, not a job. Maybe you've had it good for a long time?
