What do you mean by intentionality? In principle, large language models predict the most likely continuation to the input prompt. Intent is a very anthropocentric concept to describe a specific style and hierarchy of computation. It just parrots what an approximation function learned from training conversations.

Limiting the applications of these models, especially as they are modular and scalable, to some funny image or poem generation is very naive. It‘s not hard in principle to scale up LLM to a dynamic network of interacting agents, potentially opening the doors to never-before levels of automation complexity. Even chatgpt as it is now can basically sufficiently carry out a very big chunk of the subprocesses and provides tremendous increases in efficiency for real-life work in many different areas.

Art is the expression and self-actualization of the artist and takes a wide variety of forms. Art will exist as long as people have a complex inner life and want to express it symbolically.
