What do you think a filibuster is? It’s an active debate. So yes, you can wait one out. If they can’t continue, then their time is over and you vote. It’s why they’ll get up and read books.
To break it, you don’t move on to new topics until they give up.
That’s how it used to work, not anymore:

Still work that way. You have three options. You cloture the person, you move to new business or you wait them out. You still have the option to wait. Nothing has changed.
Waiting means nothing happens. You just wait. If it’s important enough that’s what you do.
You cloture the person
And that essentially isn’t an option at times due to how difficult it is to reach the 60 vote threshold, which means nothing gets done, which means congress is basically useless.
