Oh yeah that's way harder. I'd be OK arguing that we could fling something at Alpha Centauri and have it stop using tech with a very low-risk path from today's state of the art, but even just the 3D printing needed for self-replicating probes (such a printer has to be able to print something exactly as complicated as itself from asteroid material, which is really going to be incredibly hard to do, not to mention energy intensive) is a long, long way off and there's no way I'm going to be able to convince you of the viability of that!
