> However, it is important to ask if you want to stop investing in your own skills because of a speculative prediction made by an AI researcher or tech CEO.

I don't think these are exclusive. Almost a year ago, I wrote a blog post about this [0]. I spent the time since then both learning better software design and learning to vibe code. I've worked through Domain-Driven Design Distilled, Domain-Driven Design, Implementing Domain-Driven Design, Design Patterns, The Art of Agile Software Development, 2nd Edition, Clean Architecture, Smalltalk Best Practice Patterns, and Tidy First?. I'm a far better software engineer than I was in 2024. I've also vibe coded [1] a whole lot of software [2], some good and some bad [3].

You can choose to grow in both areas.

I personally found out that knowing how to use ai coding assistants productively is a skill like any other and a) it requires a significant investment of time b) can be quite rewarding to learn just as any other skill c) might be useful now or in the future and d) doesn't negate the usefulness of any other skills acquired on the past nor diminishes the usefulness of learning new skills in the future

I'm doing a similar thing. Recently, I got $100 to spend on books. The first two books I got were A Philosophy of Software Design, and Designing Data-Intensive Applications, because I asked myself, out of all the technical and software engineering related books that I might get, given agentic coding works quite well now, what are the most high impact ones?

And it seemed pretty clear to me that they would have to do with the sort of evergreen, software engineering and architecture concepts that you still need a human to design and think through carefully today, because LLMs don't have the judgment and a high-level view for that, not the specific API surface area or syntax, etc., of particular frameworks, libraries, or languages, which LLMs, IDE completion, and online documentation mostly handle.

Especially since well-designed software systems, with deep and narrow module interface, maintainable and scalable architectures, well chosen underlying technologies, clear data flow, and so on, are all things that can vastly increase the effectiveness of an AI coding agent, because they mean that it needs less context to understand things, can reason more locally, etc.

To be clear, this is not about not understanding the paradigms, capabilities, or affordances of the tech stack you choose, either! The next books I plan to get are things like Modern Operating Systems, Data-Oriented Design, Communicating Sequential Processes, and The Go Programming Language, because low level concepts, too, are things you can direct an LLM to optimize, if you give it the algorithm, but which they won't do themselves very well, and are generally also evergreen and not subsumed in the "platform minutea" described above.

Likewise, stretching your brain with new paradigms — actor oriented, Smalltalk OOP, Haskell FP, Clojure FP, Lisp, etc — gives you new ways to conceptualize and express your algorithms and architectures, and to judge and refine the code your LLM produces, and ideas like BDD, PBT, lightweight formal methods (like model checking), etc, all provide direct tools for modeling your domain, specifying behavior, and testing it far better, which then allow you to use agentic coding tools with more safety or confidence (and a better feedback loop for them) — at the limit almost creating a way to program declaratively in executible specifications, and then convert those to code via LLM, and then test the latter against the former!

As someone with 20 years experience, DDD is a stupid idea, skip it and do yourself a favour.

You'll probably be forming some counter-arguments in your head.

Skip them, throw the DDD books in the bin, and do your co-workers a favour.

Of those 3 DDD books - which did you find the most valuable?
