AI Thread Summary
The discussion centers on the use of UML (Unified Modeling Language) and specifically the representation of use case diagrams. A user expresses concern about stating that a function will only be used in extraordinary situations within their use case diagram. The response critiques this approach, suggesting that it is not an appropriate way to represent functionality, as it introduces conditional logic that complicates the diagram. It is also noted that the role of the Branch Manager may not qualify as an actor in this context, as merely informing an actor does not constitute an interaction with the system. The conversation emphasizes the importance of clarity and proper representation in UML diagrams.

I do not think that is the right way to represent it.

An "if" == a branch.

I think you can leave off the right branch, since/if nothing happens.

Also, I'm not sure if Branch Manager is an Actor here (i.e. a stick figure). Actors interact with the system. Simply informing an actor is not an interaction.

Thread 'Is this public key encryption?'

I've tried to intuit public key encryption but never quite managed. But this seems to wrap it up in a bow. This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.

Thread 'Who is responsible for the software when AI takes over programming?'

I tried a web search "the loss of programming ", and found an article saying that all aspects of writing, developing, and testing software programs will one day all be handled through artificial intelligence. One must wonder then, who is responsible. WHO is responsible for any problems, bugs, deficiencies, or whatever malfunctions which the programs make their users endure? Things may work wrong however the "wrong" happens. AI needs to fix the problems for the users. Any way to...
