It's not a skill about inventing anything. It's a skill that denotes overcoming some big problem that prevented human civilization from advancing. Tesla literally brought the domain of the gods (lightning) to humanity. He's probably one of the most applicable for the skill. Drake's is weird because she wasn't the first to circumnavigate the world, but according to her interlude it's about solving that problem with existing resources (with no regards to your mystery rank) and then have that solution spread across humanity to become sort of integrated into the "common sense of man", so even though she wasn't the first, it was probably more that what she did was what spread to the rest of humanity and that's why she got it instead.
