That's an interesting concept. But wouldn't the minds of many little talented people add up to be stronger than those of the very gifted ones? For example, if the majority of people had racist tendencies, would that create an racially intolerant deity? Wouldn't WW1 and 2 have automatically lead to the creation of one or several very strong war gods? Or is there a sort of threshold one has to be strong enough to pass in order to enter the cloud?
Those are good questions.
If I am to extend my thinking further, the minds of many talented people could add up if someone powerful enough created something for them to feed off of, eg. modern terrorism. It did not exist before the 1970s or 1960s. A "Jihad" was artificially created in conjunction with several people BIn Laden, the US government etc. This was based on something that already existed but twisted to suit cancerous intentions - the peaceful religion of Islam and the concept of a jihad borrowed from the time of the crusades in the middle-east. There are degrees of power obviously. I can create a new word or concept and let it out here on TBBS or the internet. Unless it captures people's imaginations, it isn't likely to go viral. Even if it did go viral, most likely would taper off. It has to have "staying power".
As for racist tendencies, yes it does add up to create racial intolerance which exists not just inside people's heads but also in the shared consciousness. But, there would be counterforces. If the majority of people are
not so racist or who find racism troubling, eventually the arc of the moral universe would bend toward justice. Eg. Hitler hated the Jews, by feeding off of the racial intolerance and by ruling through fear and military doctrine he created the holocaust. But once he was defeated, we had enormous support the world over for the Jews and their plight. This probably strengthened them, and one of the reasons enabling them to carve out a nation state.
As for WW1 and WW2, the initial skirmishes were started based on the ideas of resource grabbing, violence, battles and eventually war that already existed in the shared consciousness. It was just taken to a whole new level where
milliions ended up getting killed. And after WW2, the collective consciousness of the people, condensed into the minds of the leaders of that time decided that "War...uh, what is it good for? Absolutely Nothing, say it again now!"
I'm thinking there are levels of access. If I can access the skills of persuasion present in the cloud, then I become good at that and with that I could go about creating stuff that people could believe in and even consider as
knowledge. If it is strong and timeless, it will last. Modern science is a good example of concepts created that withstand critical examinations and tests because it is based on an underlying reality which shows consistent results on multiple experiments.
caveat: Even if my thoughts are anything approaching reality, I still don't profess to know the full nature of the cloud and it's laws.
