The Supreme Court is weighing whether a law that could ban TikTok in the United States is constitutional. Away from the court, legal and technology experts are pondering a different head-scratcher: What if TikTok is banned and people keep using it anyway?

The court is hearing oral arguments on TikTok’s bid to block a law that would lead to its ban in the U.S. starting Jan. 19 if it isn’t sold by its Chinese owner.

A potential nationwide TikTok ban could dramatically reshape social media for millions of content creators and users.
