The observable universe is a big place that has been around for more than 13 billion years. Up to two trillion galaxies made up of something like 20,000 billion billion stars surround our home galaxy. In the milky way alone scientists assume there are some 40 billion earth like planets in the habitable zone of their stars. When we look at these numbers it is hard to imagine that there is nobody else out there.

      Your argument about the nonexistence of a type 3 or above civilization is flawed why should we be able to detect their technology if we cannot imagine what it might look like (yo said it yourself). While you also offered a similar perspective at the end It still was bound to the assumption that a civilisation would develop inwards. If they would be able to utilise dark energy we would not be able to detect it since we can't even detect dark energy or really understand what it is for us its an extra term (not necessarily a constant actually the evidence points not toward a cosmological constant but rather a function) in the Einstein equations we don't know where it comes from we only know it influences the large scale structure of spacetime.

    The add before this video told me there was a tribe of natives that had never seen advanced society of any kind until WW1 or WW2 times. They thought of the westerners as God's and when the westerners left the island, the natives built wooden planes and runways to pay tribute that the gods would some day return. This is the exact thing makes me think about the pyramids, whether in Egypt or South America.

    [9:03] "Their influence would in all likelyhood be so all-encompassing and their technology so far above our own *that we couldn't miss them.* The galaxy should flash with their activity..." The conclusion you make does not seem right. How could we tell the difference between "natural stuff" and "level 3+ civilization artifacts"? Given that it becomes nearly impossible to imagine what a level 3 civilization would even look like, there could definitely be several high-level civilizations toying with our galaxy right now and the black hole at its center is actually their doing for all we know. For example, dark energy could be the scar of a struggle for control over our universe by multiple level 5+ civilizations...

    Something has been bothering me about this, and I think I figured it out. There is no reason for a species to actually achieve any of these types. We are just a type 0.75 species, and yet we are a handful of decades away from colonizing other planets. Why would a species need or want to go the full route of building a dyson sphere. If they are really that greedy and expansionist, they would skip all that and book it out of the solar system at the earliest opportunity. Infact I find it unlikely that any species will ever hit all of the milestones for any of the types.

    I think life achieved type 1 several hundred million years when it colonized land. From this perspective, the harnessing of electricity and subsequent rise of computation mark the transition to type 2: A synthetic form of life that dwells in the gravitational fields of stars and feeds off their energy, using this energy to generate simulations for humans to live in.

Lastly, In my opinion there would be nessesary to multiple advanced civilizations coexist in order to progress. But thats a human perspective, beings so advanced may be further our understandings
