Just because LLMs are a technological innovation for "going to the gym" does not make cable machines a good metaphor. Maybe cable machines with cables made of highly variable grade hemp are comparable to LLMs-- they'll break randomly, and cause unexpected friction here and there. A cable machine still involves a human doing a thing. A forklift at the gym does the work instead.

All this fluff about targeting specific muscles etc is simply not analogous to LLMS. Maybe old-school barbells are paper files and fax machines, and cable machines are Slack, Asana, and Excel?

I'll clarify.

The cable machines are efficient because they _do the work_ of performing a movement for you, much like how LLMs do the work of writing an e-mail from a prompt describing what you want to write.

They are designed to only activate the target muscle/muscle group during the movement, which is good for working that muscle but bad for working all of the other muscles that _should be_ activated in the kinetic chain for that movement.

That's the metaphor I was trying to convey.
