And they are no better than answering machines for customer service. Sure, they can answer basic questions, but so can the automated phone systems.

This is what drives nuts the most about it. We had so many incredibly efficient, purpose-built tools using the same technologies (machine learning and neural networks) and we threw them away in favor of wildly inefficient, general-purpose LLMs that can’t do a single thing right. All because of marketing hype convincing billionaires they won’t need to pay people anymore.

I’m sure all the savings from accelerated/cheaper R&D will be passed on to the consumer…right?

To save you some time: Google and Meta are monitoring the conversations using the device’s microphone

This is not happening. It is not something that would be possible to hide, there are so many different places this could (and would) be detected by someone with the right know-how (data/battery consumption in particular).

Try and pay attention to how many ads you get that are completely irrelevant to you. It will happen way more often than ones that match up with your conversations.

Neither 110VAC or 240VAC is inherently more dangerous as long as the system is paired with the right gauge of wire. As for personal safety, both are more than capable of killing you regardless of amperage. 240VAC may even be a little more capable because it can push more current through the resistance of your body.

I’ll admit, American plugs/outlets leave a lot to be desired, but it’s not any more dangerous because of the higher current.

The most pressure it would experience would be the difference in internal vs external pressure. At 1000ft of depth there’s a pressure of 440psi. Assuming the sphere somehow managed a perfect vacuum that’s still well below the 6000psi compressive strength of high strength concrete, hell they would still have more flexural strength. The spheres themselves definitely wouldn’t be the weak link.

Depends if the spheres require any steel reinforcement; the salt penetrates the concrete and absolutely wrecks rebar. Though I imagine spheres at depth (not to mention with a partial vacuum) can function like an arch and support themselves with compression, which concrete excels at.
