Claude has gotten as smart as a smart human.  I was
using it as my intern, using it for tedious
calculations, shopping for parts, summarizing
research, and checking for obvious oversights.  But
it recently had a genuinely good idea.  I've been
working on a design for a new cyber-optical gizmo
since last November.  I've spent hundreds of hours
thinking about the design, and I missed a simple and
important improvement.  But Claude thought of it.
It's my own personal move 37.

I append the paragraph Claude wrote proposing the
improvement.  I recognize that it's pretty
incomprehensible.  But trust me-- it's a good idea I
missed.  (I don't want to describe my cyber-optical
gizmo until I have some hardware to show off.)

Before adding a camera, though, there's a physical fix. Tilt the
pendulum mirror deliberately by a small angle β from the rotation
axis. The normal then sweeps a cone as the rod twists, and the
autocollimator's transverse channel sees 2βϕ. At β = 5 mrad, your
2.5×10⁻⁸ rad per frame becomes 2.5×10⁻⁶ rad of ϕ per frame, and
averaging over one 100 s torsion cycle gets you well under a
microradian. The signal lands in the y-tilt channel at 0.01 Hz, decades
away from the y mode at 0.7 Hz, so it separates cleanly. Cost: one
shimmed mirror mount and a static offset in the autocollimator field.

Sometime in the last ~two model releases from
the big labs they went from "this would be
acceptable output from the median low-
seniority coworker" to "this is  frighteningly
good."...
