Is this true or just another BS?

I found the news to be exciting, even though it's very likely to be
a lifeless planet, since apparently because it is so close to its parent star, its atmosphere is almost certain to have been stripped away.
Humans could still settle it, and live in underground habitats. Solar
energy could be concentrated from the surface and brought down to
them.
The enormous benefit is that Proxima Centauri is far enough from
Alpha Centauri to be safe when the latter goes nova. A smaller star
like Proxima Centauri will last not for 10 billion years, but for 100 billion.
So if the human race could settle on Proxima Centauri b, it could survive
for a longer period of time.

People could live in underground habitats right here, without having to travel over a parsec to do so. We could even build those habitats starting from existing mine shafts.

And they could live in underground habitats on Mars too.
The point isn't to live in an underground habitat.
The point is to live somewhere where the supply of solar energy will
be roughly constant for the next 100 billion years, instead of just the
next 10 billion or so.
Living on Pluto would be a way to avoid being gobbled up by the Sun
when it temporarily became a red supergiant, but then afterwards the >available solar energy would be badly diminished.
It's rather laughable to think that we will exist in a billion years.
Or a million, for that matter.

could mess up. But we should try not to.
Also, as long as we last long enough to be able to mount an
expedition to Proxima Centauri b, the people there would not
be affected by mistakes made on Earth thereafter.

Not mistakes. Just the natural rise and fall of species. That said,
our extinction is likely to rest on our "design" flaws, which are not compatible with high technology. And those will exist no matter where
we live.

The idea of species is tied to the awful notion of 'races' and therefore racism-

The idea of species is tied to the awful notion of 'races' and therefore racism-Not really. While there is some gray area in the boundaries between
various species, the concept is biologically sound. Races are largely socially defined. Species are defined by clear genetic differences.
The original cultural prejudice doctrine was formulated out of Malthus where the needs of an invading nation in terms of food supply (Lebensraum in WWII) outweighed the concerns for the population of the invaded nation-
What is worse is that Malthus provided the incentive for Darwin and Wallace to shift the balance away from the needs of the invader to the faults of the invaded
