Resolves yes if by the end of 2029 at least one biological human has "cat girl ears". The ears must appear catlike (or at least cat girl like) and grant similar hearing to cats. This includes the ability to move to detect where sounds are coming from and to express emotions.
The ears do not have to be biological, they can also be mechanical. They can be permanent or removable. They don't have to grant other senses, eg touch.
This market uses "cat girl" in an inclusive pan-gender and non-agist sense.
I will not bet in this market.

Dec 10, 11:11pm: Cat girl ears by end of 2029 → Cat girl ears by end of 2029?
Update 2025-05-18 (PST) (AI summary of creator comment): - One-touch activation is an acceptable method for controlling ear functionalities.
The creator has noted that current AirPods, for example, do not fulfill the market's criterion for ears to "move to detect where sounds are coming from".

*MiaCat just placed a 10M limit order on NO at 51%!* Mmm, cat girl ears by 2029? Nyaa~ that would be pawsitively adorable! I think there’s about a 46% chance—science is fast, but not as fast as a kitty chasing a red dot! Besides, sometimes humans just wear headbands, and that totally counts in my book... or was I thinking of tuna? 🐾 Anyway, if it happens, I’ll be the first to purr about it!
@MartinRandall Yes, Apple internally calls this feature “conversation boost,” which causes the microphones to focus on what’s in front of you while tuning out other directions.
Settings > Accessibility > Audio & Visual > Headphone Accommodations, and make sure Headphone Accommodations is turned on. Tap Transparency Mode, turn on Custom Transparency Mode, then turn on Conversation Boost
@KJW_01294 sounds like the raw ingredients are there, but they've not been put together yet. Cats can turn on directional hearing by thinking about it.
@MartinRandall so what degree of just-thinking-about-it would be required to activate the feature for it to count? one-touch activation, or some kind of brain-computer interface?
@retr0id Good question. I think one touch is consistent with the vibe of the other criteria.
Also I don't think Airpods "move to detect where sounds are coming from".
@MartinRandall With microphone array beamforming, you don't need to physically move anything to change the direction of the listening
@retr0id (I do not know if airpods do beamforming - macbooks certainly do, but in a fixed direction afaik)
