How to continue doing IT, a 40-year-old code farmer

How to continue doing IT, an old code farmer in his 40s.
I'm in my 40s, I'm still doing technology, and I occasionally write code.
Most of it is architecture and management.
Maybe into the 50s.
I don’t know what to do without technology.
Recently , I am studying big data technology, cloud computing technology, and artificial intelligence technology after a while.
