One of my early mentors worked on it. They mentioned the pulsation for the sleep indicator was modeled not just on the human respiratory rate, but specifically that of a sleeping adult. It came up when we were playing around with on/off dimming curves for a room based video conferencing product and discussing physical analogies we could model a curve on. Fun afternoon exploration, but in the end we just stuck with ease-in/out.
It could absolutely be false nostalgia since I was a Mac fan from about 2005 to 2009 with an MBP that had the breathing feature but this really felt like a high point for computer hardware. It felt slick and performant but still serviceable.
Ironically, after a series of uninspiring Windows machines the next laptop that made me feel any level of enthusiasm like that Mac is my current Framework 13 running COSMIC on NixOS. Quite an about face!
That light was a big deal - I remember when I got into Arduino years ago this was one of the common projects people would do to add a breathing LED to everything, including a pumpkin:
I think the sleep light on the white plastic iBook was the first product feature I truly loved.
My greatest hope is that I should be so lucky as to invent a single thing as great over the course of my lifetime.

As the post states, it was almost always accompanied by a light sensor. It always got dimmer either by that sensor or internal clock.
My desk was at the end of my bed. The MacBook with sleep light was always on that. It was never bright at night. Dimming half a second after I turn the light off. Even if the lid was closed.
Oh, also, you can swap batteries of Macs during sleep if it has a removable battery, without losing state.
In the Choose Your Own Adventure novel Supercomputer, you receive as the grand prize in a contest an AGI-capable computer and go on various adventures with its advanced thinking capabilities. One of its features is said to be a "smile light" which illuminates in a pleasing greenish color when the machine is happy. The breathing light always reminded me of Conrad's "smile light" and just went to show that Apple engineers were reading the right type of science fiction novel.

No, I won’t spoil it here. :)
I won't spoil it here either :-)

This is why Apple is Apple.
That era is long dead and gone, regardless of the current state of such a light.
I don’t think I ever thought much about that light but now after reading this article…it really was a pretty cool and useful detail.
The info about how the light’s rhythm was meant to be similar to human breathing is cool too.
I think all my laptops' LEDs first blink wildly when I close them, then change to a slower rhythm, that's not an Apple feature.
