A final word...

on chips.
Not Doritos.
Microchips.

 What exactly is the endgame here?

Knowing what we know about these cybernetic implants, we understand that they can theoretically be used to help a doctor arrive at a correct psychiatric diagnosis. That is, if the person being subjected to the implant is unaware of its presence.

The most accurate readings you would receive from something like this would take place in the time slot between implantation and discovery of the implant's existence by the test subject.

By the way, in my case, a period of 6 or more months is plenty to gather someone's "baseline."
Why don't you ask to see those records (I'm kidding, it's none of your business anyway. But it would prove my point.)?
Those would be the most accurate results available.

After the "discovery," the results are totally tainted.
Except for those moments in which you forget it's there, which happens only minutes at a time.

So, since we know that these things only work properly when they are unbeknownst to the implantee, the only plausible uses are upon people who do not have the wherewithal to understand what is happening to them. In other words, people who can be taken advantage of.

Let's say we have a child with a severe form of Autism, and their parents worry about them wandering.
This implant company goads their parents into offering their child up for this type of implantation.
While the child is sleeping, the implant is inserted.

Sure, I'm sure much could be gleaned from studying that child and others like him.
Then what?

Eventually, data would have been mined from every nook and cranny about Autism.

What's the plan then? Would they keep creating and inventing "patients" to implant, and hire one person for every chipped person to "watch" over them to create jobs? They tout job creation as an excuse for this, you know.
Wouldn't there be much less invasive ways of monitoring your special needs child?

I say "invasive" because you need a brain surgeon to fix the problem of having 0 privacy whatsoever.
Would you be willing to be hooked up to a machine for an "accurate diagnosis" only to have brain surgery later?

Probably not.
Traditional methods still work.

Even with an Autistic wanderer, don't they have simple GPS units available which could be utilized in the incidence of a disappearance?

So, just who would be the "target" of these new implants?
I'm struggling to come up with answers for this.
Probably because there are no legitimate "targets."
Unless you want to release psychopaths from prison and monitor them with some kind of pre-crime division, or something crazy like that. (Please don't. Keep them behind bars.)

This isn't about creating jobs for the American people, it's about corporations convincing you that you somehow need to purchase their product. It's about making money and the omnipresent possibility of serial abuse of a powerful product.

What if a hostile foreign power got its hands on this and implanted our president or one of our high-ranking cabinet members? We have absolutely no idea what kind of havoc could be wreaked if something like that were to ever happen. I hope it doesn't ever, but stranger things have happened.

It's a flawed product peddled on a flawed premise.
They're trying to sell something that doesn't even work properly when used legally, only illicitly.

There is no market for this.
Tell them to peddle their snake oil elsewhere.
