Long time developer and AI hobbyist here. I don't think developers have to worry for another decade at least.

We survived the inventions of high level languages, offshoring, no-code tools and probably dozens of other developer killers I forgot to list. We've been trying to automate ourselves out of jobs for at least half a century and the media takes note and reports the imminent death of the software industry, but so far, no luck.

LLMs right now might improve efficiency and reduce the need for some developers, just like the other inventions I've listed. Maybe an unforeseen invention will finally make developers obsolete, but that's always been the case. I can tell you with high confidence LLMs are not that invention.
