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?

I could be wrong but when large stars collapse I believe their gravity stays mostly the same, such that most things in orbit are uneffected.
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.
