Traditional sails are very labor intensive, I doubt they will ever make economic sense again. They also take a lot of space that most ships don't have.

The two variations that might go somewhere are kites to save maybe 10% of fuel [1], or some variation of rotor sails [2] on tankers or bulk carriers that have the unobstructed deck space.

It might happen when rich countries start imposing tariffs on cargo ships using bunker fuel. Burning that stuff is utterly terrible but it's cheap so hey.
