IMO a good idea is not only one that can be successful, but also one that can be accomplished.
For example, I had the idea of mobile payments almost 20 years ago, way before smartphones. This is extremely popular today, but even if I had had the technical skill to pull it off (I didn't) this is only the kind of idea a giant company could have considered.

Good ideas are not universally good.
