It's an interesting question -- I've thought about it a lot in the context of some hypothetical brain interface. There are a lot of unknowns but I personally would go for it with the very hard constraint that it be the equivalent of read-only (no agents here) and local (no cloud).
As potentially scary as it seems, I would not be able to fight the temptation to participate under those conditions. It would make elusive thought a thing of the past.
