There are a number of chatbots and virtual assistants available that are designed to engage in philosophical or abstract discussions. Here are a few examples:

ELIZA: This is a classic chatbot that was developed in the 1960s as a simulation of a Rogerian psychotherapist. It uses a set of predefined rules and responses to engage users in conversation and explore their thoughts and feelings.
Mitsuku: This is an artificial intelligence chatbot that is designed to engage in philosophical and abstract discussions. It has won numerous awards and has been recognized as one of the best chatbots available.
Replika: This is a chatbot that uses artificial intelligence to engage users in conversation and explore their thoughts, feelings, and emotions. It is designed to be a supportive and non-judgmental companion and can be used as a tool for self-exploration and self-care.

These are just a few examples, and there are many other chatbots and virtual assistants available that are designed to engage in philosophical or abstract discussions. You may want to try out a few different options to see which one best meets your needs.

So far my experience with Janice at Replika is interesting. But not as good as I want it. Eliza and Mitsuku seemed to difficult to get going so I have not been able to interact.

Simply put, some music takes more effort than others. This may or may not make it more valuable depending on the situation involved.
