Yes but they only performed the training on the posts and images set to be globally publicly accessible by anyone. In a sense, they took the public permissions as an indicator that they could use that data for more than just providing the bare social media service.

Isn’t the opt-out option to just not make the photos/posts globally public?

The non-cynical answer is that they’re counting contractor/vendor time in this full time equivalent answer. Which would probably be a good thing, because I imagine that the best people in cybersecurity aren’t actually employees of Microsoft.

To put it in more simple terms:

When Alice chats with Bob, Alice can’t control whether Bob feeds the conversation into a training data set to set parameters that have the effect of mimicking Alice.

Your comment missed the mark entirely.

Not sure why you’re saying that. I wasn’t disagreeing with any of your points, but adding to them another angle that answered the parent comment’s concerns about whether leaving wifi on for airplane mode drains battery. You addressed the cellular radio side, and I was adding a separate point about the WiFi radio that complements what you were saying.

Also, phones don’t use a lot of power to purely listen for Wifi beacons. They’re not transmitting until they actually try to join, so leaving wifi on doesn’t cost significant power unless you just happen to be near a remembered network.

Your scenario 1 is the actual danger. It’s not that AI will outsmart us and kill us. It’s that AI will trick us into trusting them with more responsibility than the AI can responsibly handle, to disastrous results.

It could be small scale, low stakes stuff, like an AI designing a menu that humans blindly cook. Or it could be higher stakes stuff that actually does things like affect election results, crashes financial markets, causes a military to target the wrong house, etc. The danger has always been that humans will act on the information provided by a malfunctioning AI, not that AI and technology will be a closed loop with no humans involved.

to my knowledge, Bluetooth doesn’t work with airplane mode

The radio regulations were amended about 10 years ago to allow both Bluetooth and Wifi frequencies to be used on airplanes in flight. And so cell phone manufacturers have shifted what airplane mode actually means, even to the point of some phones not even turning off Wi-Fi when airplane mode is turned on. And regardless of defaults, both wireless protocols can be activated and deactivated independently of airplane mode on most phones now.

an airplane full of 100 people all on Bluetooth might create some noise issues that would hurt the performance

I don’t think so. Bluetooth is such a low bandwidth use that it can handle many simultaneous users. It’s supposed to be a low power transmission method, in which it bursts a signal only a tiny percentage of the time, so the odds of a collision for any given signal are low, plus the protocol is designed to be robust where it handles a decent amount of interference before encountering degraded performance.
