50. Started coding at 7. I never stopped coding. In fact, the past decade saw heavy open source contribution, public speaking, etc.
I love coding with agents. Claude Code now almost exclusively. The 20x max subscription is endless until you start writing custom multi-agent processes, and even then. Still takes quite a bit of effort to burn through.
I get so much more done, and can be productive with languages/frameworks I'm not familiar with.
To everybody worried that AI will kill jobs. There have been many points in the evolution of software dev where some new efficiency was predicted to kill off jobs. The opposite happens. Dev becomes more economical, and all of the places where dev was previously too expensive open up. Maybe this time won't work out that way, but history isn't on the side of that prediction.
An experienced software dev can get multiples of efficiency out of AI coding tools compared to non-devs, and can use them in scaled projects, where non-devs are only going to compound a mess. Some of those non-devs will learn how to be more efficient and work with scaled projects. How? They'll learn to be devs.
I'd be building several side projects for myself if I wasn't super busy with the primary work I'm doing. The AI tools take over the tedious work, and remove a lot of work that would just add mental load. Love it.
