The next biggest thing I like is just the shared context from machine to machine and the fact its always running and I have given it yolo access to my local stack. Home Assistant crashes? Now the wife can ask the bot to restart it. I see an interesting HN blog, i can get it to add it to my obsidian make me a useful doc (I am starting to use the llm-wiki trend but Claude Cowork seems to be really killer for this). I see an Reddit post about some new service to run locally? I can ask it to spin up an lxc of it and configure it for my use case and it will do the wiring for me.
I will say since the killing of Claude oAuth i am finding a lot of its magic did come from Opus just being so aggressive. An example was I had a task of someone sending me an image and I would have to turn it in to a table and then upload it to this really crappy portal for my non-profit. I threw the task at Openclaw (and at the time running Opus 4.6) and i watched in real time as it reverse engineer the sites backend API and found a way for it to post the data itself and it wrote itself a python script to make it repeatable. I dont see that same kind of killer instinct of doing whatever you need to do to get the task done with other models (Codex and now MiniMax).
