I think the most likely answer is either:
a) Same reason we don't SMS other species on earth - we're first, and if anyone else catches up it'll be a long time from now
b) We can't begin to conceive of the sort of technological advances achieved by other lifeforms. The fermi paradox rests on probabilities accumulated over billions of years, but ignores how briefly human intelligence has existed - the written word is only a few thousand years old. If your species advances to the point of being able comprehend and control all of reality, is there much point in having endlessly bigger LCDs powered by your awesome discworld, built by your giant starfleet? Is our faith in the inevitability of endless growth and expansion not itself a sort of primitive cargo cult?
If the entire process of going from advanced social being with primitive tools and language to a post-physical singularity takes on average 50,000 years, the drake equation need changing
Good point, something that I have not contemplated before. It makes sense: If we evolve to the point where we can control reality, why would we be concerned with expanding and travelling the universe?
It is almost like saying: "You can do anything and become what you want to become." What do you choose?
