What does Matthew 11:23 mean?

And you, Capernaum—do you think you’ll be lifted up to heaven? No, you’ll be brought down to the grave. If the miracles done in you had happened in Sodom, that city would still be here today. Matthew 11:23 - Modern Text Bible

(He warns Capernaum that their privilege doesn’t guarantee safety; even Sodom would have survived if they’d seen such miracles.)
