If you want a stable language that matches with lower stress jobs try Java and work for an established B2B company. Lots of established B2B companies have Java based products they built a few years ago and they need people to work on those products. Assuming they have a healthy revenue stream, they are going to be focused on keeping the system stable and keeping their customers happy. They aren't going to be chasing the latest fad or the updating their Java version as quickly as possible. One benefit is that if you dislike your job, there are plenty of places looking for Java programmers. Compare that to COBOL, where the market is tiny.
