Sure, but mightn’t there be several plausible long horizon plans?

Here’s an example: I had asked Claude for some music recommendations in a certain style. Part of its output was:

—

*Long journey tracks*

Clinic — “The Return of Evil Bill”

Guided by Voices — not really, wrong band

Silver Apples — “Oscillations”. Proto-everything, deeply repetitive, hypnotic.

—

So at some point there, the next token produced was “Guided” or “Guide” or whatever, and then because it can’t go back, it had to correct itself after the fact.

Reasoning/CoT have helped a lot, but I feel like small versions of this still happen all the time.

Human writing is like 90% editing.

It can but it is limited because it's only got a single pass through the network to fit the entire "longer horizon plan".
