One fear I have had about DSoNE is that a hole in the dike that allows the exchange of energy beyond our 3space might explain the Fermi paradox. Rossi's reactors do appear to be incredibly unstable and allegedly meltdown or explode. Maybe those events plug a hole which, if it grew larger, could create a flood.
There is a factor in Drake's equation for those civilizations which destroy themselves. Lemuria and Atlantis maybe got a little too close?
