It may only be 5% of people that care about space exploration by itself but a lot more will care if we’re lucky enough to only get a house sized impactor as a warning shot. At that size there’s a hope that there would only be severe property damage and no loss of life.

Chelyabinsk should have been that wake up call but most people don’t think about it deeply enough to realize how much worse it can be.

If we’re unlucky then the first big impact we experience will be our last.
