New Technology Uses Lasers to Transmit Audible Messages to Specific People
If you want a sound in your year, you get a device for that. If you are a business wanting to notify people who trust you, you can give them devices or blast a speaker. This fills the use case of an actor distributing information to people who do not have enough contact or trust with that actor or who do not want the information (because they would willingly use their own device if they did). Most likely use cases: punitive or targeted spam, punishment (security alarm, military grade crowd repellent, thief targeting, etc). Also possible: misinformation, generating confusion and chaos, making people feel schizophrenic. Weapon in the making. Good uses are also possible - targeted communication to people who can’t hold devices (surgeon during surgery, vr headsets, helmet headphones, etc, but that’s too cheap a use case for such an expensive laser, so weaponization is more likely.
