I'd rather hone my skills at writing better, more intelligible code than spend that same time learning how to make LLMs output slightly less shit code.

Whenever we don't actively use and train our skills, they will inevitably atrophy. Something I think about quite often on this topic is Plato's argument against writing. His view is that writing things down is "a recipe not for memory, but for reminder", leading to a reduction in one's capacity for recall and thinking. I don't disagree with this, but where I differ is that I find it a worthwhile tradeoff when accounting for all the ways that writing increases my mental capacities.

For me, weighing the tradeoff is the most important gauge of whether a given tool is worthwhile or not. And personally, using an LLM for coding is not worth it when considering what I gain Vs lose from prioritising that over growing my existing skills and knowledge
