This reminded me of woolion's comment from ~4 months ago citing a note about this from the original manga.

This hands thing, there's a literal note in the manga about it. The man is an old neuro-scientist, but new brain implants that allow for direct CPU connectivity is something that only young neuro-surgeons are familiar with. For this reason, this man doesn'n't want a man who could be his child to operate direcly on his brain. However, the productivity boost because of the brain implant creates a gap between humans and augmented humans, so this is the solution this man found to work around his refusal to get the brain implant, and so it is clear that it is a fairly bad solution that only exists because of this human "motivation". The two points are some of the major themes that are explored in depth.

This kind of goes against the author's point about the hands / keyboard being a brain interface, however, given the fact that the brain ultimately controls most actions humans take, there's still some truth to what the article presents in that all keyboards are a type of brain intreface.
