Age discrimination in software does happen but it's not as prevelant as it can seem reading about it online.

There are still plenty of jobs for people in software at basically all ages. For now at least the problem tends to be too many jobs and not enough supply of people to hire.

At the end of the day what you want? A certain salary? If you define what it is people here can tell you if it's reachable in software (it probably is) and how. A certain type of work? Just tired of working in software?

It might help if you defined the end goal in a little more detail.
