I think the argument comes from the full title being "The United Kingdom of Great Britain and Northern Ireland". If you drop NI then the other three countries can already be grouped under the Great Britain term.
I wonder how much effort it would be to put together something expanding on this that's really friendly to new developers exploring a system. The goal would be to have something that looks more like a traditional swimlane diagram, but with human readable labelling of the connections. The open telemetry data should provide a nice skeleton and then maybe use some LLM summarisation (with access to the source code) to label what's going on.
Retrieval augmented generation. In short you use an LLM to classify your documents (or chunks from them) up front. Then when you want to ask the LLM a question you pull the most relevant ones back to feed it as additional context.
Prices have dropped quite considerably recently. You can now pick up an e-bike as cheaply as €500. Once you get out of the "budget" range I'd expect to be paying more like €1500 for an average one.
