And even then you could do aimbot with camera pointed on the screen and either faking a mouse or providing sensor sufficient data somehow to simulate movement... That is reach super human reaction times and accuracy...
How attached and how technical does it have to be to be "cyborg".
Me with a pen and paper exceeds many human capabilites.
Likewise with wearables like a smartwatch.
Does it have to be direct neural integration to be a cyborg? Definitely people with profound brain injuries have been enhanced to the ability to interact again.
Good question! IMHO, it's a spectrum, of course, not a binary concept.
But if we have to define a criteria... I guess, integrated just enough so it can't be trivially removed, making it more of a "body part" rather than a "tool".
Point is, it'll certainly spark a discussion and re-evaluation of what's "fair", potentially shifting the consensus from somewhere around the current "glasses are fair game, but a programmable mouse is not" to somewhere more accepting of differently-abed individuals.
