We should not have an entire industry of 10,000,000 devs reinventing the JS/React/Spring/FastCGi wheel. Im sure those humans can contribute in much better ways to society and progress.
I'd have said the opposite. I think LLMs facilitate disposable code. It might use the same paradigms and patterns, but my bet is that most LLM written code is written specifically for the app under development. Are there LLM written libraries that are eating the world?
The code itself is not clean and reusable across implementations, but you don't even need that clean packaged library. You just have an LLM regenerate the same code for every project you need it in.
The LLM itself, combined with your prompts, is effectively the reusable code.
Now, this generates a lot of slop, so we also need better AI tools to help humans interpret the code, and better tools to autotest the code to make sure it's working.
I've definitely replaced instances where I'd reach for a utility library, instead just generating the code with AI.
I think we also have an opportunity to merge the old and the new. We can have AI that can find and integrate existing packages, or it could generate code, and after it's tested enough, help extract and package it up as a battle tested library.
E.g. let's say I'm working on a production thing and features/bugfixes accumulate and some file in the codebase starts to resemble spaghetti. The LLM can help me unfuck that way faster and get to a state of very clean code, across many files at once.
Could potentially mean just a change in time allocation/priority. As it's easier and faster to locate and potentially resolve issues later, it is less important for code to be consistent and perfectly documented.
Not fool proof and who knows how that could evolve, but just an alternative view. One of these big names in the industry said we'll have AGI when it speaks it's own language. :P.
