@Ron_Ron, I think it is interesting to think about how many truly original ideas that a project might contain, and how many of them may be remixes of a lot of different elements from projects that have been done elsewhere.
I would say, if it can be studied and researched, then it can’t be a truly original idea. I think that it is possible to create original and unique objects by combining existing ideas. You do this very well.
Most of my successful projects have taken elements from other sources, and adapted them to incorporate other elements, or for production using a different method (which is usually the laser-cutter).
Most of my ideas that I would consider actually original, have been hard to implement due to being overly complicated (or just plain bad).
I think that creativity is a skill that can be cultivated—@Ron_Ron, you are a prime example of this. I also think that many people feel that they are not creative because they think creativity requires coming up with original ideas.
What the original quote leaves out, is that very few scientists have truly original ideas. When they do have them, they must engineer a study to prove them. So as @Grant-Fraser pointed out, maybe Dyson is a bit to self-aggrandizing with his view on good scientists.
