It is from 2017 but it was new to me:
https://en.wikipedia.org/wiki/Aestivation_hypothesis

The aestivation hypothesis is a hypothesized solution to the Fermi paradox
conceived in 2017 by Anders Sandberg, Stuart Armstrong and Milan M.
Ćirković. The hypothesis, published on 27 April 2017, suggests advanced
alien civilizations may be storing energy and aestivating (hibernating in
times of heat instead of cold), until the universe cools to better make use
of the stored energy to perform tasks.

As the universe cools, the potential work producible by stored energy can
increase by a multiplier of 10^30 per Landauer's principle. If the goal of
an advanced civilization is to maximize the number of calculations done, to
generate information processing for tasks like mass-producing simulations,
then aestivation would be purposeful to achieve this end.[1][2][3]
