It sounds like you predict life evolves to create dyson spheres. If that's the case, then once all energy is harnessed by this civ, then they won't show up to us anymore.
I agree, I appreciate that I am able to see it via his website. I'm just confused as to why the line is drawn.
One has to assume that all of these lovely devices consume MASSIVE amounts of energy in order to function, and we as a species are already having problems managing the "scant" resources we have. Make the warp drive, even just one, and we get MUCH further toward the rest of the tech than the other way around.
Also, reaching other planets and/or system to obtain more resources is possible with this tech.
I am skeptical given that the forum link is down, and that something as simple as USB run code breaking open the hypervisor seems shady.
