Not SAC, the original GitS movie.

> I love thinking of this as such a wonderfully naive early 2000's view on HCI — there's no direct-access data API

Even in original GitS, both cyborgs and bots have wired neck ports and can also communicate wirelessly, both subject to various kinds of attacks. Even if not intended, this typing may constitute a legit airgap defense.

Wow, that's an angle I had absolutely not thought of before. Of course they "could" just jack right in, but that's probably forbidden -- the only permitted interface is the keyboard? Maybe? That's pretty intriguing!

An analysis of the layout and usage of the so-called tera-keyboard:

Worth a read, notably the estimated achieved speed in comparison with a human brain. I won't spoil you, but it allowing chords has... consequences.

The article also asks how a human brain could process such interaction so fast; well in GITS canon cybernetised brains are augmented/enhanced beyond normal human abilities.

The article also raises the question of why this and not a direct connection. I would yet again argue the possible security implications, notably in the context of the Puppet Master being around.

But it could also be a gracefully degrading interface, and a less cybernetised person may still be able to operate it with normal hands, or even a non cybenetised one, albeit of course at a massively reduced speed.

IOW ed is the standard text editor / it's a Unix system, I know this. After all, what better interface than text via stdin/out to scale from normal hands/eyeballs to max line rate?

EDIT: the first comment actually raises both interop and security concerns!
