It's wild, you'd be hard pressed to find any truly new ideas.When my bro was 15 he thought he invented turning headlights, then read in an encyclopedia that Mercedes Benz did it in the 40's.
I know this is seriously off-topic, but there exists a school of thought that there is more to our world and more to our existence than just a 3 dimensional world with the individuals thoughts isolated from others by the uniqueness of individualism, DNA and the privacy of the mind.
Some say that there are no individual thoughts and information collectively flows through the human species at a level outside of our 3 dimensional world.
It's a massively hard concept to grapple with and i struggle to accept that it could even have any truth, but there doesn't seem to be any level of unique invention attributable to the individual, because when researched, there's always someone or a group of people that have come up with ideas or concepts previously developed or discussed at an earlier time.
When you have your eureka moment; waking up in the middle of the night; thinking to yourself - that's it, i've come up with a world changing invention, is it really you, or more to the point, your mind that has created, as an isolated entity and completely on it's own, a ground breaking idea or conceptual technology never thought of before.
If the concept of "time" or the "progression through time" is stripped away so that there is no "yesterday and no "tomorrow", where does the concept of "the process of thought" start and stop; when there is no barrier to the notion of having to wait for tomorrows invention, because it's all just sitting there waiting to be accessed by your mind trapped in a 3 dimensional world and body.
It's way, way off-topic, and it's a idea that's just too hard to even grapple with.
Now i'm just waiting to wake up in the middle of the night for my eureka moment, but i suspect that when i happens it will not prove to be a unique idea; never thought of before.
