In other words, it's a skill issue. LLMs can only make this worse. Hiring unskilled programmers and giving them a machine for generating garbage isn't the way. Instead, train them, and reject low quality work.
The way I explain this to managers is that software development is unlike most work. If I'm making widgets and I fuck up, that widget goes out the door never to be seen again. But in software, today's outputs are tomorrow's raw materials. You can trade quality for speed in the very short term at the cost of future productivity, so you're really trading speed for speed.
I should add, though, that one can do the rigorous thinking before or after the doing, and ideally one should do both. That was the key insight behind Martin Fowler's "Refactoring: Improving the Design of Existing Code". Think up front if you can, but the best designs are based on the most information, and there's a lot of information that is not available until later in a project. So you'll want to think as information comes in and adjust designs as you go.
That's something an LLM absolutely can't do, because it doesn't have access to that flow of information and it can't think about where the system should be going.
This is an important point. I don't remember where I read it, but someone said something similar about taking a loss on your first few customers as an early stage startup--basically, the idea is you're buying information about how well or poorly your product meets a need.
Where it goes wrong is if you choose not to act on that information.
Ahh, well, in order to save money, training is done via an online class with multiple choice questions, or, if your company is like mine and really committed to making sure that you know they take your training seriously, they put portions of a generic book on 'tech Z' in pdf spread spread over a drm ridden web pages.
As for code, that is reviewed, commented and rejected by llms as well. It is used to be turtles. Now it truly is llms all the way down.
That said, in a sane world, this is what should be happening for a company that actually wants to get good results over time .
