Asymmetric News

It won't be available for purchase in 2024

Tracks sleep

It won’t have a USB-C port

will support wireless charging

Improved health tracking if you pair it with an apple watch (ie better data if you wear both than either by itself)

It will only be usable with an iPhone

It will be available in a range of colours

It’ll measure blood oxygen saturation / include a pulse oximetry function.

Will support gestures

At launch, the MSRP will be <$500.

Tracks Stress

The ring design will be asymmetrical.

It will eventually be tied up in litigation like the pulse-ox sensor on the watch

There will be a gold version (real gold, not just gold colored)

battery lasts over a week

It will have a physical button on it

It will have a glass or crystal screen

There will be a higher memory model sold for more money at launch (think 128MB vs. 256MB models)

Waterproof up to 100 meters / 330 feet

It will be called the iRing

It will have a camera

It will be announced in 2025

It will be available for purchase in 2024

Different observers may have time's arrows pointing in different directions

Anthropic selection: observers necessarily find themselves in regions with increasing entropy

The arrow reflects brute initial conditions; there is no deeper explanation to be had

Growth of quantum entanglement under unitary dynamics explains thermodynamic irreversibility

Gravitational instability and cosmological expansion generate the observed thermodynamic arrow

Inflationary cosmology dynamically selects special low-entropy initial conditions, explaining the arrow

Entropy increase is emergent from coarse-graining and typicality; no deeper micro-physical asymmetry is needed

Time’s arrow arises from asymmetric boundary conditions at both temporal ends (two-time boundary conditions)

The Past Hypothesis is a fundamental lawlike assumption, and a low-entropy beginning fixes the arrow

Landauer’s principle and information-erasure costs make entropy increase a consequence of information processing constraints

Computational irreversibility and algorithmic complexity growth are the deeper source of the arrow

Penrose’s Weyl curvature hypothesis: near-vanishing initial Weyl curvature sets the gravitational arrow
