If a person in 1900 wrote a novel about landing on the moon, they would be a sci-fi author.

If they discussed what a future moon landing might be like or how it could work, they would be a futurist.

If they were raising funds for a moon landing that they are currently working on, and success is surely imminent, despite not having any evidence that they can achieve it, or that they have beaten the technical hurdles necessary to do so, then they would be seen as a fraud.

It doesn’t really matter that at some point in the future the moon landings happened.
