I'm a 48 year old developer. I'm currently doing a bit of contracting on the side while starting my own company. I can still see myself doing this in another 10 years despite my current rate of decline. Most 50+ developers "having a pretty bad time" have made the following mistake: They became highly paid experts in technology that was important when they were 30. Focus might work out for you, my uncle made a boat load of money in the late 90's when he was 58. Mostly because he was an expert Cobol programmer. But more than likely you will regret it in 10 years. Stay current. Stay passionate. Stay active on Slashdot, HN, or whatever the next one is. I'm currently building using Django/jQuery/Bootstrap. My last project was GAE. I love what I do.
