We’ve seen before that big leaps forward in technology can bring down industry titans, like the cellphone pioneer Nokia.

It would be better for all of us if Big Tech wasn’t an absolute and invulnerable force. I’ll see the wobbles of TikTok’s clones as a sign that it’s still possible for Big Tech to fail.
