I've been writing software for 30 years, a part of it had success in the sense of being widely known and adopted for a long time. Writing software is difficult, consumes time and is difficult as you get older to focus the needed time away from other matters like a professional life and family.

With LLM, my productivity suddenly went up x25 and was able to produce at a speed that I had never known. I'm not a developer any more, instead feels like project manager with dedicated resources always delivering results. It isn't perfect, but when you are used to manage teams it isn't all that different albeit the results are spectacularly better.

My x25 isn't just measured on development, for brainstorming, documentation, testing, deployment. It is transformative, in fact: I think software is dead. For the first time I've used neither a paper notebook nor even an IDE to build complex and feature-complete products. Software isn't what matters, what matters is the product and this is what the transformation part is all about. We all here can write products in languages we never had contact with and completely outperform any average team of developers doing the same product.

Replaces the experts and domain specific topics? Not yet. Just observe that the large majority of products are boringly simple cases of API, UI and some business logic inside. For that situation, it has "killed" software.
