What that long philosophical post is about, that thinking that much just leads to questions about existence, and Christian religion has answers.
Spending too much time with computers can cause thinking, that everything is a computer. It is not. Being a human has all feelings etc extra stuff. Watching Matrix movie too many times can make someone imagine we are in Matrix. We are not.
It is just, that world is going through hype bubbles, when everything at news is just about one topic: 1. Corona, 2. War, 3. AI.
AI is about pattern matching. Calling many old stuff with new name AI, just to sell stuff. Making it up as they go.
AI is just some hardware and software, human written answers, recognizing text/image/etc and matching it with some answers. But it only answers what it is asked about, and makes up something that may not be true. So there is need for humans that try to understand is that answer useful or not. Humans will be always needed, to help verify answers are not too dangerous.
If AI asks AI, that kind of system usually causes AI to hallucinate more and mess up usefullness of that AI model. If AI would "think something", it needs checking, is that useful at all.
AI can not take over the world, those thinking that has just watched Terminator movies too many times. Most important data is at offline local networks. Every online service is busy adding more security protections and trying to always stay online.
AI, as software, is useful for many purposes. It is a new tool. New tools helps in many kind of work. This has happened many times, like after horses there were cars, it can change what kind of work is needed. There is big need for more coders. Coders are needed to debug code, check does code have vulnerabilities. AI tools help programmers to figure out some syntax, like Bing AI helped me to convert SQLite SQL Query to MongoDB query. Just do not copy paste propietary code and secrets to AI chat.
There is no magic. Magic means, you are using some technical terms, and writing unclearly, just to hide something, to sell some stuff. The same can be written in easy to understand language.
