I have no problem with experienced senior devs using agents to write good code faster. What I have a problem with is inexperienced "vibecoders" who don't care to learn and instead use agents to write awful buggy code that will make the product harder to build on even for the agents. It used to be that lack of a basic understanding of the system was a barrier for people, but now it's not, so we're flooded with code written by imperfect models conducted by people who don't know good from bad.
Where are you encountering all this slop code? At my work we use LLMs heavily and I don't see this issue. Maybe I'm just lucky that my colleagues all have Uni degrees in CS and at least a few years experience.
We're in a transition phase, but this will shake out in the near future. In the non-professional space, poorly built vibecoded apps simply won't last, for any number of reasons. When it comes to professional devs, this is a problem that is solved by a combination of tooling, process, and management:
(1) Tooling to enable better evaluation of generated code and its adherence to conventions and norms (2) Process to impose requirements on the creation/exposure of PRDs/prompts/traces (3) Management to guide devs in the use of the above and to implement concrete rewards and consequences
Some organizations will be exposed as being deficient in some or all of these areas, and they will struggle. Better organizations will adapt.
the number of experienced, senior programmers though, who are in “anti-LLM” camp, is still fairly staggering.
