If im not mistaken i remember Michio Kaku saying that we will reach type three in about 1 million years from now where humans can build dyson spheres and harness the energy from galaxies, where we would be able to send robots to search other galaxies and then create gateways for the actual type 3 civilization to travel through to them. We are currently as he states it at 0.7 and our greatest challenge is to break past the type 1 where it is the most violent, like a child moving into their teenage years. Looking at the state of the world today we are kind of doing so, where type 1 allows humans to harness and completly understand the power of the planet (solar, wind, kinetic) we are developing systems to help us harness it however we just need to ensure we dont obliterate ourselves before we get there.
