Neuralink is not a startup, it is a research lab dabbling in a very speculative area. Something might come out of it in the very long run, or it might not. The demo showed essentially a tool they are using in this research, a miniaturized brain implant which is technologically superior to what competing researchers are using. They showed an application of that research tool, a recorded session (not included in the actual demo, probably hard to reproduce) where they claim to have "predicted" the movements of a pig. "Predicted" is probably a strong word since the brain controls motor functions.

So they showed progress and proved they are actually a lab and actually perform research. That being said, there was absolutely nothing in the demo remotely related to a "brain-computer" interface, nor are they likely to get there for many, many years. That's the speed when doing hard science, and pumping more money only has a marginal efect.
