For the last 20 years of my career, I have prided myself on keeping a clean codebase, making 'art-not-science' decisions of when and what to abstract, scope boundaries, then implementing them cleanly, specifically to be easily grok'd by other developers. But after building, from scratch, and operating an (essentially) vibe coded software solution (in typically a very engineer led/low level space) over the last 9 months, I am still able to move at super-human speeds in terms of delivering features, investigating and fixing any issues (there aren't many, certainly less than most human teams I've been in) - whether that's because of AI advances or just their innate quality of being able to tackle the dross coding tasks that always got avoided by humans in my past I'm not sure but I'll stick with it until a better approach becomes apparent!

I feel my specialist skills (coding, debugging, devops) has been devalued - I can't justify holding those as my value-add proposition any more - but new skills are replacing those (context/AI/agent engineering) in equal measure.
