75歳までプログラミングは可能
I'm 58 and have been continuously employed as a software engineer since my 20's.
Even now I can find new jobs. I have watched friends & colleagues wind up in the
situation of being unemployed (e.g. due to being laid off and being unable to find
new work). Generally this was due to them getting complacent, staying at one
place too long, and not keeping skills current. I've consciously avoided falling
into this trap by continuously learning, changing jobs when no longer growing
in my current job, and preferring start-ups (which tend to be new development
using new technology).
I'm 54. Got my current job when I was 52 (prior to that, 11 years at Microsoft).
I think if you're not over-specialized that you can still do well. Doing be a person
who just writes device drivers, or just does web stuff, or just writes toolchains.
Do it all, and at depth when you can.
I tend to get into projects that are 2-3 years in scope and involve actually
shipping new technologies at consumer scale. This will teach you all kinds
of interesting things, from fundamental product underpinnings to making
devices manufacturable.
Keep coding, that's for sure. It's not a young person's game if you keep
at it. My father in law retired, a firmware engineer, at 75.
