Yes meeting new life species is not a smart move.
We can barely get a man to a planet closet to us, let alone to a new solar system for the time being, and probably for ever, we are not capable of doing these things people dream of, increasing funding is a waste of time.
Besides, look at the Voyager 1 and 2 probes, it's been 30+ years and it barely left our solar system, going at speeds that will most likely harm a human being if they are on the spacecraft.
