Agentic coding is just doing for development what cloud computing did for systems administration. Sure, I could spend all day building and configuring Linux boxes to deploy backend infrastructure on if the time and budget existed for me to do that, and I'd have fun doing it, but what's more fun for me is actually launching a product.
It is very easy to notice at work who actually likes building software and wants to make the best product and who is there for the money, wants to move on, hard code something and get away with the minimal amount of work, usually because they don't care much. That kind of people love vibe coding.
For instance, I recently had to replace a hard-coded parameter with something specifiable on the command line, in an unfamiliar behemoth of a Java project. The hard-coded value was literally 20 function calls deep in a heavily dependency-injected stack, and the argument parser was of course bespoke.
Claude Code oneshotted this in about 30 seconds. It took me all of 5 minutes to read through its implementation and verify that it correctly called the custom argument parser and percolated its value down all 20 layers of the stack. The hour of my time I got back from having to parse through all those layers myself was spent on the sort of programming I love, the kind that LLMs are bad at: things like novel algorithm development, low-level optimizations, designing elegant and maintainable code architecture, etc.
For more complex modifications, I would have taken the time to better internalize the code architecture myself. But for a no-brainer case like this, an LLM oneshot is perfect.
It's not so trivial to verify that the change doesn't cause problems elsewhere, where it also should have been propagated.
You raise a good point: an important skill in effectively using LLMs for coding is both being able to recognize ahead of time that cases like this are indeed simple, but also recognizing after the fact that the code is more complex than you initially realized and you can't easily internalize the (side) effects of what the LLM wrote, warranting a closer look.
