Actually, since the heavier elements are at lower levels in the suns
"mantle", stripping off the higher levels will "age" the sun, by
increasing the percentage of heavier elements. This is likely to
increase the cyclic instability, creating more violent flare seasons,
known as "Maunder Maximums", as well as the possiblity of minor novas,
which are like huge flares. Since our sun is so small, it is not likely
to supernova, however to puny life forms like ourselves, a mere nova
flare of short duration would fry at least the half of the earth facing
the sun, and cause huge storm systems to arise sweeping round the planet
that make HUGO look like a minor depression. Not a good outlook to say
the least. For the half of the planet that survived, they would have at
least 40 days and nights of rain.

yeah, I don't know if you've ever read Larry Niven, but he loves these
sort of concepts. His Ringworld, Ringworld Engineers, and recently
released Ringworld Throne all are set in a world that is a band of
superstrong matter circling a star. THe band is 100,000 miles wide, and
as big round as earths orbit. Its got thousand mile high walls on the
sides to keep the air in by centrifugal force. Something like 35
trillion sq. miles.
unfortunately, solid structures orbiting a planet or star are unstable,
and are therefore impossible without some active measures to adjust
perturbations in the orbit caused by this natural instability. All such
ring or shell structures would eventually precess to the point of
contacting their primary catastrophically (what a way to go out, eh?).

Not only ourselves, but enabling everyone to reach their maximum
potential. Our resource base here on earth is too small if we wish to
retain our ecology (yeah, oxygen would be nice! And food too!) and
spread a western lifestyle with all the technical doodads to the whole
world. yeah there's plenty of resources availble if your willing to
scrape the crust up, but that does not seem like an elegant option. What
then? SPACE, beat your ubermachinas to the best real-estate.

Hey, its how you make it. If we choose to be part of the solution rather
than part of the problem, then it will be no problem. i see a greater
problem with >H fuedalism developing, the "god" chosen versus the
slugs. If we continue to be exclusive amonst ourselves, or confiscatory
towards the most capable, then when and if AIs develop, they will wizz
right by us as we continue the old arguments. Everyone needs to realize
that not only do you need to teach starving people to fish, but they
need to pay their teachers tuition for the lesson.
Suggested readings:
A Darker Geometry, by Mark O. Martin and Gregory Benford, based in Larry
Niven's Known Space Universe
Suggested music:
Burden, by Soundgarden. Included here as a MIDI file for your listening
enjoyment. I found it to be rather dynamically optimistic.
