It feels different if you replace "LLM" with "outsourcing". Thing is, instructing a team of software engineers what you want is a lot more work (they need a lot more handholding), a lot more expensive, and a lot slower. But I'd argue that the work is the same - writing specifications, adjusting accordingly. Minus the human factor.

LLM coding agents won't kill software development as a job, but it will affect outsourcing and agencies as an industry. Of course, outsourcing companies will / are using it too.

The difference is that before nobody forced you to be the manager of outsourced team, either you're fired or you're still working with code. Now you'll be expected to generate everything and oversee 10 agents.

>LLM coding agents won't kill software development as a job

They won't same as the industrial revolution didn't kill farming as a job but it sure did ate up most of the farming roles. Most of the people you have ever met are people who would have been farmers had they been born before the revolution. Developers without much leverage, underpaid, overworked and competing with hundreds of experienced devs for a single role is likely to be the eventual future of most software development thus gradually becoming similar to other stem roles in terms of pay, competition and negotiation power.
