I don't know what street I'm on. That's probably a red flag of some kind.
I make myself stop walking--it's surprisingly difficult, another bad sign--and make myself go over the doctor's advice again. They told me after the operation that I needed to be vigilant, because even though the neural implants would correct the... the cognitive deficiencies, my brain supplies just a little too slowly... that I suffered after my motorcycle accident, there were vulnerabilities in the cybernetic systems that were unavoidable. Exploits and back doors that a skilled, a skilled s-something, someone, someone who uses exploits to, to, to... shit. Lost it. That's probably a pretty bad sign too. I haven't experienced that kind of brain fog since the operation.
Technically speaking, I didn't consent to the operation that restored--no, not restored, more like supplemented--my intellect. My family had to do it. Don't get me wrong, they asked me for permission, but I wasn't considered legally capable of consent due to the severe neurological impairment I suffered when my head slammed into the tunnel wall at sixty miles per hour. My helmet kept my skull mostly intact, but the only thing keeping my brain from hitting the front of my skull that day was a thin cushion of cerebrospinal fluid. It wasn't enough. Most of my memories between the accident and the experimental surgery that inserted a fine mesh of networked computers directly into my nervous system come back to me through a haze of confusion, even now.
Confusion. Shit. I was confused about... about something. I'm having trouble remembering what it was. That's a warning sign, isn't it? The doctors, they told me that I shouldn't experience any problems holding a train of thought. The network has multiple redundancies, it should be able to handle the workload even if up to half the nodes fail. And I, I'd get signals. From the failed nodes. Danger signals that I was experiencing issues with the system that required immediate attention from a qualified medical professional.
I look around, still not recognizing the neighborhood I'm in. Was that what happened? Did I come here looking for a doctor? I rub my temples, my fingers brushing the little bump of the wifi antenna as I try to massage some sense back into my fuzzy thoughts and unaccountably patchy memories. It doesn't seem right. None of this seems right.
I'm not getting the danger signals. I mean, I'm getting danger signals--my feet are moving again, and that's a pretty big red flag that something's wrong with my brain right now--but my supplemental neural network isn't warning me of any node failures or processing problems. I know what those sound like; they ran diagnostic tests on me for weeks back at the hospital, triggering every conceivable alert and system warning until I got used to hearing the voice inside my head without panicking or wondering if I was going insane. If I was losing my ability to think, or worse to control my body, the network would tell me.
But it's not. I'm walking down an unfamiliar street in a neighborhood I don't recognize, with no real memory of how I got here, and my cyborg brain thinks that's just fine. And I... I don't know if I can figure this out without it. Without the network, I'm. I'm not very smart. I have trouble holding onto a thought, I have trouble remembering things. The doctors, they told me I might never regain my full mental capabilities, even after years of therapy. Too much brain damage, they said. The cells couldn't grow back. I recall how much they had to dumb it down for me and I can feel myself tearing up.
Is that what happened? Did the whole network fail at once? That's not supposed to be possible. The doctors said it had a one in ten thousand chance of even a single node failure per hundred thousand hours of use, and there were over a million independent nodes in the interconnected network with failsafes to contain any kind of cascade effect. That means the chances of a total crash are--are--
I sob in frustration. I can barely even picture the individual numbers, let alone turn them into a mathematical equation that would give me the probability I'm looking for. Even before the accident, math wasn't my strong suit, and afterwards I needed someone to help me make change at the corner store. I've gotten so used to having a supercomputer in my head to handle complex calculations that I'd completely forgotten just how infuriating incomprehension could be.
