Personally I don't think either of these approaches will actually bear fruit
Yeah, I ere on the side of pessimism on us ever contacting another intelligent species. It's fun to still try it, but the math is staggeringly against us. Even with trying to detect radio waves from another solar system, radio waves have their limits on how far away they can be detected before the cosmic background covers them up. The odds of us picking up on radio waves from another planet are... not good.
