Can't wait till rogue arrays of lasers start beaming advertisements directly into your ear while walking down the street.

Yep, this is going to be Altered Carbon or Ghost In The Shell type of crap. Whatever you Google for will follow you everywhere , and nag you until you buy it...

Precedent suggests that it'll nag you after you buy it... maybe both.

Lasers can also record sounds through window vibrations. Now they can be targeted transmitters too. They could continuously record and transmit sound and tailor the messages to real time conversations. Seems like high potential for abuse.

For example, sharks with giant fricking laser beams that convert shark thoughts to audible sound that gets louder based on target's voice level.

Or government, millitary, and adtech abuse.

I'm not a big regulations person but see value in them in this case.

Reminds met of the book series Daemon by Daniel Suarez [0], only there they use nonlinear acoustics to get this effect (if I remember correctly). Nice books, nice ideas by the way.

Edit: They call it Hypersonic Sound System, not nonlinear acoustics, see [1].

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: p…

Those depressing sentiments reflect an unfortunate reality of our time. The world wasn't always bloated with spammy advertising, and I'm hopeful that fad will eventually give way to more human-friendly business models.

Yes, any new technology comes with potential for abuse. But I'm still excited that maybe one day this tech could be miniaturized enough (or deployed responsibly) to give me wireless virtual earbuds without having to stick anything in my ear.

Or I'm a spy and I know people will be triggered by on body devices...

There are stories of people having their orthodontic braces act as a radio antenna. Only the person with the braces would hear something. This writeup is short: https://www.recordonline.com/article/20091118/Health/9111803... . There's also a (busted) Mythbusters around picking up radio signals thru fillings.

It would be so cool if that's the way how radio technology was discovered.
