Get better camouflage so we don't get get found in the Dark Forrest. https://en.wikipedia.org/wiki/Dark_forest_hypothesis

>The name of the hypothesis derives from Liu Cixin's 2008 novel The Dark Forest, as in a "dark forest" filled with "armed hunter(s) stalking through the trees like ghosts". According to the dark forest hypothesis, since the intentions of any newly contacted civilization can never be known with certainty, then if one is encountered, it is best to make a preemptive strike, in order to avoid the potential extinction of one's own species. The novel provides a detailed investigation of Liu's concerns about alien contact.

Following that:

> The Berserker hypothesis, also known as the deadly probes scenario, is the idea that humans have not yet detected intelligent alien life in the universe because it has been systematically destroyed by a series of lethal Von Neumann probes.

Yeah but they clearly didn't do a very good job on Earth so how systematic could they be?

Don't get me wrong, it's a wonderful premise for a book which can simply mobilize a plot device to brush this problem aside. However, if we want to bring the conclusions back to reality they have to undergo a customs inspection which flags said plot device.

The solution is that the probes were built by a long ago technological civilization on Earth as a desperate measure in an interstellar war.

The probes are out there and were programmed never to come back to Earth.

That's a solid plot device and sounds like a fun story! It definitely doesn't pass the customs inspection for use in speculation about the real world, though.
