For everyone in the comments assuming these will be unrepairable I... don't think they will be? As far as I can tell this has zipper teeth on cord instead of tape. I don't see why that'd be impossible to hand-sew. It might be a bit more fiddly because it'll be more flexible. If anything it'll be much easier to seam rip existing zippers because you can just put the seam ripper between the teeth and cut the cord instead of the stitching.
The proprietary sewing machine does seem like it's not amazing competition wise, but if you think Chinese manufacturers aren't going to have a clone the second this becomes popular you haven't been paying attention. It'll basically be a sewing machine that does a zigzag stitch with a modified transport so the needle doesn't hit the teeth.
The one thing I do think is a disadvantage is that this style of zipper would put limits on how thick the fabric it's attached to can be. Normally the tape goes between the sides of the runner, but now it's the actual garment fabric. Might have implications for wear too.
