> calculating the volume of a prism-like polytope between it and its projection

There is the key insight that you don't need to explicitly compute this projection.

As long as the weights are open, who cares? You can rely on someone else for inference.

No offense but your title is not informative at all.

High blood glucose causes a host of bad health issues even in non-diabetic people: visceral fat, liver fat, inflammation, cardiac disease... You don't need to wait to be diabetic to embrace good dietary habits, and a glucose monitor would go a long way helping people make that transition.

I imagine they plan to rely on debt, which is the fashionable thing to do these days.

The wake up call might be difficult, for the whole country or even the whole world.

Preventive medicine is a bit one. If your fitness watch could measure blood glucose, I think it would be a ton more impactful in terms of health outcomes.

I'm pretty sure there is a lot of code in Android that belongs to Google and is not part of an upstream GPL project. They would be completely entitled to stop sharing it.

This should be a golden opportunity for hackers like us to keep rebuilding this stuff and get bought.

A huge waste and completely demoralizing though.

You can reuse the app indefinitely, for cheap, and predictably. I would say these are huge advantages.

I would say the tooling plays a part. Where are the go-to open source solution that a beginner can turn to without too much research?

At this stage, it's easier to block them with uBlock and move on.

I don't have a lot of confidence for legislative solutions. Although I admire people who keep trying.

Unless someone comes up with a brilliant optimization strategy or new hardware that renders all that inefficient Nvidia crap overnight.

Privacy aside, who wouldn't want their $8,000 cloud device abruptly shut down when Weave Robotics decides to pivot?

Do we have any evidence that Tesla is actually working on manufacturing millions of robots?

I wouldn't be surprised if they had new models up their sleeve. Could be wrong of course.

This doesn't mean anything. All LLM output is like that.

That said, I agree that LLMs are terrible at grading stuff, except perhaps if you give them a very detailed evaluation grid.

Contrast one regulation vs. thousands of litigations by companies who don't always have the expertise or budget to pursue complex legal procedures.

This in turn introduces a lot of economic inefficiency, for no good reason. I think regulation would be useful here.
