So in the long run, all that we have built will build and thought of building will pretty much be worthless since we have would cease to exist?

You’re correct. The mass stays the same when a black hole forms so anything in orbit will stay in the same orbit.
The sun won’t turn into a black hole though. You need at least 5 times as much mass as the sun for a star to turn into a black hole.
