All hardware becomes legacy hardware in time. Even if we assume they’re eventually able to deliver on all those great big shiny promises, I’d rather not have to schedule an outpatient surgery just to keep up on emails. Pocket touchscreens being practically mandatory is bad enough…
Someone paralyzed from the neck down for whom this enables the use of computers, which they before couldn’t do, probably would rather have the outdated model than none
Would they still want it if it became hackable and someone could do nefarious things to them which they no doubt will try?
That’s up to the individual, I don’t think there’s universal answer to that. If it eventually makes it possible to restore a person’s sight, hearing or the ability to walk, I’m sure most would take the gamble.
There are people out there with short-range, wireless pacemakers with no security. Most just provide information you’d expect but some of them are also defibrillators (they can kill). As far as I know none have been harmed in an hacked attack but a hacked brain implant brings to mind more than just killing the owner. We may have an interest as a society in making this illegal because it’s not worth the gamble to us for people’s actions to be hijacked remotely.
I highly doubt that someone disabled enough to need implants like this is capable of doing damage to anyone but themselves. Like if you’re interested in protecting them, sure I’ll accept that. But the idea that society needs to protect itself from this is silly.
I don’t understand how one could think brain implants is a totally safe invention for a society. Did you consider more possibilities than just manipulating people into to physically attacking others?
Did you? Because you haven’t named them.
