Breakthrough Starshot's method of laser propulsion still has many technical hurdles needed to be crossed.

So I'm wondering what you guys think the first forms of relativistic spacecraft propulsion are likely to be.

Whether Breakthrough Starshot's laser propulsion will come first, or whether other methods of propulsion will progress faster and give us those relativistic speeds of maybe even up to Lorentz factors of +10-20%.
