The only way to future-proof any creative and complex work - get awesome at it.
It worked before LLM it will work after LLM or any new shiny three-letter gimmick.
If companies can get the final output with less people, and less money, why would they pass on this opportunity? And please don't tell me that it's because people produce maintainable code and LLMs don't.
If you don’t get it - you are not lousy, just not experienced enough or as I say - not doing engineering. Which is fine. Then your fear is grounded.
Because only the non creative professions like devops, sre, qa to some extent, data engineering to some extent are at _some_ risk of being transformed noticeably.
