We usually see this kind of discussion around weekends. To me it looks a bit like psychological warfare, designed to drive up the mega valuation of some IPO candidates, in other words: to make LLM based systems more valuable by bashing an entire class of workers.
I don't quite believe in the doom scenario: a lot of stuff depends on the correct functioning of software. However language model don't have a complete model of reality, they won't be able to evaluate if a given change is sufficient. Therefore systems based on language models will not be able to provide complete solutions - for some time to come. There will still be quite a bit of work in software development.
