Given the relativism (conjecturism?) involved with the hypothetical existence of advanced humanoid worlds far older than ours (on a scale of perhaps billions of years), is it not feasible that our inclusion into this "Galactic Club" would give to humanity a significant evolutionary boost? (something analogous to hitting the nitrous on your souped up drag car?) How about things like ships X c5 or immortality? Machines that make us humans look like rats. Indeed, a species with a billion plus years head start on us could do some truly amazing things. And if we could find them, why wouldn't they want to share their gadgets? They would certainly not be making us a threat to their livelihood by doing so.
