Like the January 6 question, I’m assuming that anyone who had a neuralink would likely be ineligible for any sort of clearance to access information like this.
I am not as certain. Sure, Musk and his product are no longer 'cool' given his move to US political right faction, but tech is tech. Some tried banning cell phones and whatnot and the old guard there had to adjust their expectations.
In short, I am not sure you are right about it. If anything, and I personally see it as a worst case scenario, use of that contraption will be effectively mandatory the way having cell phone is now ( edit: if you work for any bigger corp that and and want to log from your home ).
As far as I am aware, no electronic devices from outside, and no devices that transmit anything, are allowed in these high security areas. That’s inclusive of cell phones, for example.
That is: the point I am making is more nuanced than whether something is popular (like cell phones or other tech).
Oh, I am sure there are restrictions for the rank and file, but the higher ups with such access can ( and apparently do ) get exceptions[1] and while this is one of the more visible examples, I sincerely doubt he is the only one.
