I can't know if you've actually used these tools, but it requires a pretty high level of creative mind to get them to produce the content you're looking for. Maybe you as a user of an LLM you don't need to be creative in the writing of words for example, but you instead need to be creative in how you control the tools and pick the right outputs, feed it back, copy/paste/cut it, change stuff, extend it.. and the same with the image generators. There's a HUGE amount of creative accessories around them to manipulate and steer the process. There might be less creativity needed with the pen, but it's needed in other ways.
