I agree with you, I too am skeptical about Neuralink being useful anytime soon.
The augmentation in my vision, at the beginning at least, is external. I don’t attempt to modify the brain. I externally “record” a persons life. A simple manifestation of such a augment would be a wearable device: Google Glass.
It follows you around and forms “memories”. This external augmentation, then is able to store, index and retrieve relevant memory at scale, with speed, and aid brains normal abilities.
Hopefully its easy to see that such an external augmentation is better than pen-and-paper based memory system.
I unfortunately did not. I am also unable to locate the message I sent you! Maybe its because I am new to this site.
