Like seriously tho. Is it really possible to combine multiple system with different platform and languages into one single system? Are there any examples in real life?
Sure it is. You just need a LOT of glue.
Every program has inputs and outputs. So to join multiple systems together, you need to write some code that connects the two. For example, maybe you can configure one system to export a CSV file with data. Then you have a script (Python, Bash) that runs periodically checking for new CSV files, and takes any files it finds, and submits them to another system.
The problem with doing that, of course, is it becomes very messy very fast. Imagine writing lots of little scripts to connect all the different programs. So many moving parts and so much stuff to keep track of.
Potentially what Ai did was to write one super program that knows how to interface with all the different systems. Basically a management/automation program that connects to everything else. Now, you might have to build your own interfaces for this. Let's say she wrote her management program in Java, but one of the systems she wants to control has a C# API. In that case, you could write a small C# program that exposes a REST/Web API, that basically replicates what the C# API allows. Then, in her Java program, she writes some code to send instructions to the C# web API.
Now that I'm thinking about it, that sounds like a really cool challenge; build a management system, and then build all the different interfaces to the different applications it needs to manage.
