ELI5: When building a skyscraper, which parts does the architect do, and which parts does the structural engineer do?
gpt
An architect is responsible for basically how everything looks. What color everything is, how the rooms are laid out, overall design, how the space feels and is used, and basically, the "Human Side" of things. 

A structural engineer tells the architect that his crazy design will collapse under it's own weight, and provides solutions on what can work. And they'll go back and forth until a solution that the architect likes and won't fall apart is reached. 

As a side note: An architect is sort of the "supervisor" of the project. They usually hire the electrical, structural, civil, and mechanical engineers needed for the job, as well as the contractors who build it, and provide overall guidance of the project. Kinda like a director of a movie.
