> planning every last detail before writing code is boring

Not only that but you can't really plan everything. It is impossible. Without LLMs, with every line of code you are making a decision or discovering something new that must be dealt with or realizing how the current thing might impact something else and so on.

There is no way for a programmer to consider all of these little things ahead of time and if an attempt is made, it will take as long as actually writing that code.
