Yeah, their institute just put out a quarterly update a few days ago: https://www.fhi.ox.ac.uk/quarterly-update-summer-2017/ . It mentions their previous Fermi Paradox paper, "That is not dead which can eternal lie: the aestivation hypothesis for resolving Fermi’s paradox" ( https://arxiv.org/abs/1705.03394 ), and also a "future paper" that sounds like this one:

> Anders Sandberg, Stuart Armstrong, and their co-author Milan Cirkovic published a paper outlining a potential strategy for advanced civilizations to postpone computation until the universe is much colder, and thereby producing up to a 10^30 multiplier of achievable computation. This might explain the Fermi paradox, although a future paper from FHI suggests there may be no paradox to explain.
