 Most people take it for granted that we have yet to make contact with
an extraterrestrial civilization. Trouble is, the numbers don’t add
up. Our Galaxy is so old that every corner of it should have been
visited many, many times over by now. No theory to date has
satisfactorily explained away this Great Silence, so it’s time to
think outside the box. Here are eleven of the weirdest solutions to
the Fermi Paradox.
There's no shortage of solutions to the Fermi Paradox. The standard
ones are fairly well known, and we’re not going to examine them here,
but they include the Rare Earth Hypothesis (the suggestion that life
is exceptionally rare), the notion that space travel is too difficult,
or the distances too vast, the Great Filter Hypothesis (the idea that
all sufficiently advanced civilizations destroy themselves before
going intergalactic), or that we’re simply not interesting enough.

His No.7 - All Aliens Are Homebodies
is the retreat into virtual worlds suggestion that I rather fancy at present.
"Massive supercomputers would be able to simulate universes within
universes, and lifetimes within lifetimes — and at speeds and
variations far removed from what’s exhibited in the tired old analog

He mentions one thing I hadn't heard before. - Sandberg probes (from
you know who).
The suggestion here is that when a civ gets to the stage that it can
create self-replicating probes to go out and spam the universe,
another thought occurs..... What if another civ has already done this?
So to ensure that nobody bothers them, advanced ETIs could set up a
perimeter of Sandberg probes (self-replicating policing probes) to
make sure that nobody gets in.

Neat idea.
