Imagine that "cool" in the vernacular applies to things that in some positive way show evidence of unexpectedness i.e. KL-divergence from ambient or correlation-surprisal in bits. These might include:
- a blank or low-noise canvas (e.g. provided by that new carpet or that freshly painted fence),
- smart engineering (e.g. found in that Mercedes-Benz or that new i-phone),
- informed/evolved connections (e.g. discovered at a school reunion or in a new job),
- and what else?
- keen, nifty, rad, amazing,
- appealing, spiffy, neat,
- just right, fashionable, in sync,
- correlated, together, unflustered,
- less random, chilly, heat sink,
- and what else?
- available work e.g. in the form of food and gasoline,
- the variety of species and number of niche-layers in a community,
- and what else?
