We need certain fundamental technologies to even think of building a generational ship. Like a power source that can last thousands of years. we haven't even built a spinny space thingie yet. Also, we lack the rockets to get that amount of material in space—also lack of space fabrication.

You can easily put a nuclear recator in outer space. It has been done any times. The issue is the longevity required.
