I remember about ten years ago taking a leisurely stroll one sunny early Spring day in the Northern Virginia woods and, suddenly, the quiet was shattered by a tremendously loud roaring noise. I looked up and there, a couple thousand feet over my head, against the purest of blue skies was the sleek white triangle of the British Air Concorde taking its final flight back to England, which it reached about three hours later.
To make interstellar flight practical for humans, we will need to find a way to travel through space that is proportionately as great a leap forward as my walking pace to supersonic flight. But, some day, I think we will. It's just in us to do that sort of thing.

Not quite yet. According to NASA, it won't happen for another 14,000 years. Still in the Oort Cloud.
