RE: Everything we do has an impact for the rest of our lives? Decision rules and decision trees
An algorithm is only as good as the person who is "programming" it or setting the rules. Even the most sophisticated AI needs some rules or parameters according to which success is measured, right?
A personal algorithm just for you "to create the perfect diet without having to spend many many hours creating spreadsheets, doing research into nutritional science, medicine, health, etc," - wouldn´t that require an equally lengthy period of programming/learning before a meaningful output can be expected?
Here is a hint, the best algorithms don't come from the mind of the programmers. The best algorithms are from nature itself. I don't when I'm looking for an algorithm, decide in a vacuum what it should be. I might have a hypothesis or an idea initially but the algorithm forms itself from iterative improvements, measurements, improvements, measurements, etc so that over time you arrive at an algorithm which was far more efficient than what your brain could come up with.
Algorithms use the latest data or knowledge to improve themselves. The programmer merely types in what they discovered. Of course you can also say math is invented not discovered and that it's all abstract from the mind of the programmer and this wouldn't necessarily be wrong. I just think it's math and math can be checked by anybody to see if it's correct or incorrect.
The data exists. It's just no being used to improve the diet of the individual. Lots of data exists about what you like to eat, what your blood tests results were, what your composition is, what your imagining test results are such as your CIMT, CT, Ultrasound etc.
So the data is out there and you can use that data to for example say that your arteries are 10 years younger than your numerical age or 10 years older than your numerical age. And if you combine all data points you might even be able to estimate the biological age. This is implying that your age is something measurable rather than an arbitrary number.
Rules are needed but the good news is most of the rules and formulas are public knowledge already. I can tell you lists of formulas which if you plug certain data in you can get different estimates out. The problem is having to do it manually. A personal trainer knows these formulas but if you have to build your own spreadsheets and track everything yourself it just takes more time. AI could track numbers, just wear your fitbit or your wearable + app, and it will track certain numbers on it's own, and those numbers go into different equations, different formulas, and then the output is beautified with what you'd think of as AI but it's really just a bunch of number crunching and easy stuff.
More sophisticated AI can do much more and automate more, but it depends on the size of the knowledge base. For example a knowledge base with a lot of knowledge about medicine can act like an expert system if it has things set up right and you ask the right questions. This sort of AI already exists if you search online, but it's just not being used in a way where anyone can access this sort of thing and use it for their sorts of problems. There isn't any AI for example to help most people with moral or social dilemmas.
As in my example, if you ask any personal assistant if you should be friends with a certain person it will not help you. You're suddenly completely on your own here. But it will tell you where to go eat? It will tell you how to get there?
