Mental implants that provide data storage, wireless connectivity, mathematical calculation and other features are a possibility for the near future.
Computers are fast
Certain operations (data storage & retrieval and mathematical operations) computers can do very much faster than humans. In most cases, computers can solve the problems posed by humans faster than human minds can pose the tasks to the computers.
Computers are literal
Human language is often ambiguous. Human minds use many techniques to put conversations/requests into context and interpret what is being said.
Often humans aren't capable of using a natural language to convey information to computers because of the ambiguity inherent in the human language.
Because we can't train computers to speak "human" we train humans to speak computers. Even with the fancy implants, Max will require extensive training in how to use and communicate with them on anything more than a rudimentary level.
You might consider the language for communicate with the implants as a sort of scripting or programming language. As Max develops methods for getting what he wants from the implants by using this "scripting" language, Max will probably develop a sophisticated suite of self-made shortcuts.
Compared to other humans who get the same implants as Max, only at a later date, Max will seem like a magician when he can use his already developed library of utilities to get what he wants.
Human brain interface
The suite of developed scripts will commonly act as a buffer between Max's mind and a direct connection to the internet. He can use his brain to select and queue up jobs to run. Those can be data acquisition, analysis, filtering, etc. He might not / probably won't monitor the processing in real time but will set up the job, get notified when it finishes, and then review the results.
Remember the sum of information on the internet now is staggering so a big part of the scripts job will be to filter out the unwanted information and just get the information that Max needs to Max.
Not so fantastic uses
Unlike the hopeful image you've given (able to diagnose any disease), medicine is far less deterministic than you might think:
- Many diseases and conditions share symptoms
- People with the same disease condition present with different
- Disease and conditions interact in unpredictable ways
- Human immune responses are different
- Drugs have different activity in different people
- Disease and conditions respond differently to the drugs used to treat
- Drugs interact with each other differently in people
Max's internet connection might give him a list of 2000 reasons that he has a headache and a decent filter might reduce that to 20 reasons and even suggested a course of treatment that works for all 20 of those reasons. Still that treatment might fail.
The same goes for physics, engineering, and any other subject. If these subjects were so easily deterministic, then the world wouldn't need scientists and engineers. We'd be able to do it all with Google searches.
In fact one of my biggest complaints about the way search engines have partially ruined humanity's mind is this:
For some topics, it is necessary to have a reasonably good understanding of a topic and the information that goes with it to even pose a good internet search for what you want. If no one commits things to memory (e.g. saying they can just do an internet search), then they miss out on the ability to solve certain classes of problems - they'll never have the information they need to pose the query in the first place.
What does that leave?
- Information collection and analysis
- Very rapid solving of numerical problems
- Able to manipulate the "internet" environment around them (with so
many devices allowing you to control them through the internet, this
could have interesting ramifications)
- Instantaneous communication with anyone anytime
- Good time sense
And another thought
When you deprives some people of social media, they suffer addiction like withdrawal symptoms.
What would happen to Max if he went into an area with no wireless access (e.g. a nature hike)?
