"50 to 100 billion years from now the universe will be a dark and lonely place," surmises Avi Loeb.

Since, with the naked eye, we can't see much beyond our galaxy, this scenario is untrue.  The
local group and our galaxy itself are gravitationally bound and are not flying apart.  Except for
heading  into the Great Attractor, which may gobble us up by then anyway.

...distant galaxies will
be travelling away from us faster than the speed of light -
a rare exception to the rule that nothing can go faster than light.

They aren't travelling at the speed of light.  They are sitting there.
What is happening is that space is expanding between us.  And
space expansion is not limited to the speed of light.

I don't think I know more than a professor of astronomy,
so put this down to dumb reportage. :)

In a few billion years the distant galaxies will be redshifted down into background and will be dimmer as well. All that will remain, even to the most powerful telescopes of that theoretical day will be 1000 or so of the galaxies in our neighborhood now. And the remaining galaxies will be kind of run-down, just a few weak stars here and there. On the plus side, it will be a quieter, more reflective time.
