Ideas are the result of a process: brilliance / talent / skill leads to understanding and insight, which identifies valuable needs and lacks, which then get synthesized into an idea.
The idea is the final product of that process, that's why it's normally dismissed as worthless. An idea by itself is like the combination to a lock for a case you don't have, which is in a place you don't know.
