Oh, but they do need the money. The goal of the company is to maximize profit for the shareholders.

The "maximizing shareholder value" idea is a recent and inaccurate belief. https://www.fastcompany.com/1680174/maximize-shareholder-val...

Corporations are beholden to their shareholders. This is an obvious and undisputed fact, rather than a belief.

The article you linked questioned the legal and ethical justification for this fact, not its accuracy.

I've become totally superstitious (convinced, even) that phones are listening to more than just ultrasound. There have been too many uncanny situations where youtube or google have recommended results that were far too specific to the conversation happening moments before. For example, one time I was telling my girlfriend about fourier transformations, something she'd never heard of before. She typed "Fo" into her ph…

No common friends, but college girlfriend recommended as potential friend on Facebook is my creepiest data mining moment ever.

What about friends who are two degrees of separation? I suspect your social graphs are closer than you might realize.

Is it possible to damage human hearing with sufficiently loud pulses above 20Khz? Most search results point to a miniscule wattage delivered by typical ultrasonic noises, but controlling for wattage, I feel like it might be possible to overdrive a high-frequency pulse to deliver more wattage in the same range. Also, relevant: https://en.wikipedia.org/wiki/Cinavia

I don't know but I would say that if the ear does not pick up the energy above 20khz, then it cannot be harmed either.

Well you would be wrong.

Your eyes are also unable to see infrared, or ultra-violet, yet either with sufficient power will blind you. In fact it's often much more dangerous than visible light, because the light won't trigger your blink reflex.

Sound is just vibration in the air, and if the pressure is high enough, you're going to suffer. High frequency ultrasound is used for various medical treatments, most of which involve localised killing of cells.

Why does android trust developers so much? Just lock down the apps already, and make microphone usage obvious.

The real question is why does Android along with most other operating systems distrust the user so much. If the user were regarded as important facilities would be provided to enable the user to control the applications.

Users would revoke permissions needed to show ads on apps that have no reason to access the Internet.

Also experienced something like this. Had a discussion with a work colleague on a particular topic, and on getting home and going to youtube, the top recommended videos were all on that topic

I don't think the word "fact" means what you think it means.

These are like modern day ghost stories.

Do you really think they're running constant speech recognition on all phones, apparently unnoticed so far, just to recommend YouTube videos?
