Of course many comments in this threas are exaggerated; there won’t be played any ads into your brain.
But there are some implications for the usage of Neuralink that are worth thinking about it - especially when it comes to privacy:
Given that it “just” runs with firmware, so that the implant can function in a way most stable and reliably, and also given that there will be no subscription model involved into all of that, will the user (patient) be able to control the functionality of the implant (e.g. controlling the intensity of the eletric signal sent out from the implant to counteract the intensity of a tremor)?
And how will that happen? One thing I could think of is to control the implant with a smartphone app. How good will that smartphone app be? Will it be programmed sloppily like these apps we know from Internet-Of-Things-Apps and have a ton of bugs? Are those (medicinal!) apps secure in terms of privacy? What is with the product support? Will the implant be discontinued after a few years (and also the app)? What if your smartphone fails (no power or hardware failure, or after an update it doesn’t work)?
A friend of mine has an app to monitor her blood sugar. She is not qute satified with the app. Luckily the provider of those diabetes sensors provided a separate device, so that the app is just an addition for measuring when you are travelling, for example. But in their last iteration they tried to omit the separate device, probably in order to save costs. My friend had to explicitly ask for it.
With that in mind I’m not keen on having control on such medicinal devices with a smartphone only. If the smartphone fails, there would be no backup. Will such similar things be the case regarding Neuralink?
I think this is because it is pretty boring to film a computer in action, because it does noting - it doesn’t move for example. So beeping sounds were added for every action a computer would do: opening or closing windows, transferring files to a disk, calculating,…
These sounds were added at a time computers were not that common in every household and to emphazise that the computer is doing something. In recent movies, computers are more silent.
Another thing film makers did to show interaction with a computer is the constant usage of the keyboard. Every thing is done with the keyboard. Open a window: type 5 sceonds on the keyboard. Transferring a file onto a disk: type the whole bible on the keyboard. This was done because it would be pretty boring to show someone use the mouse or drag-and-drop files.
It its somehow compareable to the movie trope of constantly reloading a gun. You can see this often in older movies: the protagonist is going inside a building and he is reloading his gun. Then he stops a the corner of a hallway and is reloading the gun again - despite no shot has been fired. This was also done to show the audience that a gun will be involved.
