Senior developer skills haven't changed. Wrangling paragraphs of business slop into real technical requirements, communicating these to various stakeholders, understanding how all the discrete parts of whatever system you're building fit together, being responsible for timelines, getting the rest of the team coordinated/aligned and on-track, etc.

Actually coding is a relatively small part of my job. I could use an LLM for the others parts but my employer does not appreciate being given word salad.

with the ai age, i think its also making sure team members use ai in similar was to get repeatable results
