I basically agree that most complexity lies in correctly formulating ideas -- though depending on language, there is a great deal of time and effort wasted on the overhead of expressing those ideas.

For example, Javascript's stdlib has long lacked tools for simple data transformations (group array items by a function, transform values of an object by a function, etc). These operations can still be accomplished, but only by writing bug-prone manual transformations or using third-party packages like Lodash. There is no standard idiom for expressing these ideas, which causes significant overhead.

No-code/low-code, in contrast to general purpose languages, is savagely optimized for idiomatic expression of a small set of ideas, at the expense of the ability to express any arbitrary idea.
