On Inventions by Black Americans

Well they were inventions created by black Americans. Everything's cumulative. They weren't the first, nor were they the last to make improvements, but they made their contributions.

It's like, many of our richest ideas are built upon over many years. What's important is that the inventor/creator gets compensated for their work. As that's why there's patent and copyright.

What distinguishes a true inventor/creator from a fraud, is it's their original idea. They witnessed it, and created it through their own design. By measure of human communication and what's possible, there's going to be similar ideas and inventions. Like Fairyland has reminiscent aspects of William Blake, and The Fifth Angel's Trumpet is a lot like Heinlein's Starship Troopers, since it was based on the movie, and it kind of developed in the same vein as the book--albeit unintentionally. 

Like, Star Wars, Dune and Foundation are all practically the same story. It's just different iterations, which is fine. That's how we ought to work. You can retell a story over and over again, and add in new layers of nuance and detail. Like the Song of Songs archetype is the story of every lifetime and Rom Com, but it's different every time, based on the characterizations and nuances of the plot. Same thing with the Western and Romance. What's important, is that the author--if they're original--or the inventor--if they're original--get paid for their work. As if they don't, that's when the system is failing.

True creation is mimeses, not mimicry. It draws from primary sources (nature and form), and not secondary or tertiary sources (copying and plagiarism). Or quaternary, (outright theft).
