I've been thinking about that comparison as well. A common fantasy is that civilization will collapse and the guy who knows how to hunt and start a fire will really excel. In practice, this never happens and he's sort of left behind unless he also has other skills relevant to the modern world.
And, for instance, I have barely any knowledge of how my computer works, but it's a tool I use to do my job. (and to have fun at home.)
Why are these different than using LLMs? I think at least for me the distinction is whether or not something enables me to perform a task, or whether it's just doing the task for me. If I had to write my own OS and word processor just to write a letter, it'd never happen. The fact that the computer does this for me facilitates my task. I could write the letter by hand, but doing it in a word processor is way better. Especially if I want to print multiple copies of the letter.
But for LLMs, my task might be something like "setting up apache is easy, but I've never done it so just tell me how do it so I don't fumble through learning and make it take way longer." The task was setting up Apache. The task was assigned to me, but I didn't really do it. There wasn't necessarily some higher level task that I merely needed Apache for. Apache was the whole task! And I didn't do it!
Now, this will not be the case for all LLM-enabled tasks, but I think this distinction speaks to my experience. In the previous word processor example, the LLM would just write my document for me. It doesn't allow me to write my document more efficiently. It's efficient, only in the sense that I no longer need to actually do it myself, except for maybe to act as an editor. (and most people don't even do much of that work) My skill in writing either atrophies or never fully develops since I don't actually need to spend any time doing it or thinking about it.
In a perfect world, I use self-discipline to have the LLM show me how to set up Apache, then take notes, and then research, and then set it up manually in subsequent runs; I'd have benefited from learning the task much more quickly than if I'd done it alone, but also used my self-discipline to make sure I actually really learned something and developed expertise as well. My argument is that most people will not succeed in doing this, and will just let the LLM think for them.
