We are still within his estimate window; he hasn't missed it yet. Giving ambitious public goals can help to create some urgency around finding solutions. It's not all that dissimilar to Kennedy claiming we'd make it to the moon within the decade back in 1961. I'm sure he has his skeptics as well. Without a target, and the expectation being decades, it can easily stretch on forever as teams bike shed around various things. Will SpaceX hit their target... who knows. But it's not like it's a vaporware company that hasn't made any progress. Dismissing everything they've done so far based on an assumption that they will miss an ambitious target set 14 years ago just seems like being a hater.
