Futurology

You want to give it access to your brain??? Imagine if someone hacks your brain computer interface Elon Musk!

Yeah, I foresee his implant giving its wearers some pretty gnarly cases of meningitis. I occasionally have to fix a halo device onto people with the use of skull pins. Basically a stainless steel pin that presses through the skin, making a small indention into the bone to grab onto.

The pin sites are super prone to infection, not exactly easy to keep the scalp sterile. Plus, the scalp is actually fairly elastic and moves around quite a bit. Anything that impedes the scalp from moving naturally typically causes a lot of irritation, which typically causes infections.

With the skull pins it's not that big of a deal. We can easily move the pin to a different site, and it's not like we've actually pierced the skull or the protection of the blood brain barrier.

Elons implant transects the blood brain barrier, creating an opening for bacteria to actually make it to The brain. It's basically the equivalent of walking around with a spinal tap.
