I can't think of any reason why they would do that other than specifically to prevent looping.

> The DIY community and industry are not in opposition, says Lewis.

I would really like to believe that, but given how Medtronic and every CGM I have used have seemingly intentionally sabotaged open source loop compatibility with every new product, it doesn't seem like everyone's on board...

I have an AndroidAPS. This is how it works. If the phone loses contact for any reason the device just falls back to delivering insulin at a fixed rate as normal.

> put a spotlight on the big pharmaceutical companies that had brought them to market — especially Pfizer and Moderna

Moderna? The research startup that had only recently IPO'd and didn't have a single commercial product before covid? Seems weird to call it a "big pharmaceutical company".

I'd rather a few founders become billionaires from a successful startup than have Moderna gone bankrupt and lose the vaccines they were developing forever.

Medical professionals worry a lot about "compliance". It would not be unusual for a doctor to unironically believe that "leverage" like this—forcing the patient to come in for a check-up instead of letting them make their own decisions—actually benefits the patient. So it's not necessarily about money, but that's not imo saying it's much better.

Yes, that's a pretty obvious confounding possibility. It's foolish to draw any causal conclusions from a correlation between 'wealth' and 'choice mindset' when the causality could clearly go either way.

Why Musk what? The point is that it's not about Musk. We're talking about whether Musk "deserves" his billions in profit and the answer is it's not about Musk, and it's not about "deserve". It's about all the people who benefit because of the existence of spacex/tesla/etc, who wouldn't benefit if we refuse to pay for the work of intelligent investment (by, say, seizing profits), because that would prevent their existence in the first place.

Certainly, if you think you can identify people who are particularly qualified to pick good ideas and make investments in them, it's not a bad idea to give them some money (but where do you get that money? hopefully not somewhere with negative externalities such as stealing it from different random business owners). Although structurally it's better if the billion itself is given as an investment instead of a gift, because then the person giving the billion has "skin in the game" themselves. Which is basically what I think VCs do, although I don't know how effective they usually are.

(Yes, this whole thing assumes a regulatory framework where businesses that have negative externalities or are otherwise bad for the world do not make profit. Indeed, companies that use dark patterns or rent seeking tactics to make profit should be legally punished, and if such punishments make them bad investments it's a good thing, because it means they were on net bad for the world.)

Providing up-front funding for crazy ideas like electric cars and reusable rockets when everyone else is too stupid and shortsighted to is itself productive activity. In fact it is the most important productive activity: figuring out what to do, what is a good idea, and being willing to bet the returns of your previous labour on it and wait.

The return on investment is the payment it is in our self-interest to give for this activity, because we want and need such work to be done (so that we can make use of the fruits of such ventures, instead of getting nothing at all when wealth is squandered on bad ideas or just plain old consumption).

Oh, you're right, I misread that part.

It's interesting how spot-on Coinbase's 'prebuttal' was (https://blog.coinbase.com/upcoming-story-about-coinbase-2012...). There's very little in the NYT article that isn't mentioned. The only point of inaccuracy seems to be that the story was published on Friday morning, the day right after the prebuttal, not Sunday as originally suggested. Maybe the prebuttal forced NYT's hand?

It's an online algorithm. It's meant to be used on essentially infinite streams of data, such as a live dashboard of latencies of a running server. In that context, providing a 5 element, or any finite list as an example seems like a non sequitur.

Your examples do relate to problems the algorithm actually has in this application, but they manifest as things like "extremely large warmup time" and "adjusting to a regime change in the distribution taking time proportional to the change". For instance if your data is [1000, 1001, 1000, 1001...] then it takes 1000 steps to converge, which may be longer than the user has patience for.

However, the algorithm does always converge eventually, as long as the stream is not something pathological like an infinite sequence of consecutive numbers (for which the median is undefined anyhow).

Parent said "influence desired career paths", which is not the same as differences in performance. People choose a career path for many reasons besides ability, such as individual personality, ability in alternative jobs (note the quote in your first link which points out that "girls outperform their male counterparts on achievement tests in stereotypically feminine subject areas"), or even their experience being bullied in high school with regard to the job.

Furthermore, if you want to come to valid statistical conclusions about whether a discrepancy is due to a particular cause (and can't just do a RCT), it's not enough to just ignore plausible confounders until they are "provable". You need to systematically control for all possible confounders.

> Everything's optimized for tiny cellphone screens optimized for text.

That sounds great tbh. Not everything needs to be a 4MB bootstrap.js webshit that doesn't even load with adblockers enabled.

To add to the other comments: because giving a placebo is essential for the experimental results to have any validity, not giving a placebo would be imo way more unethical, since it would mean you are exposing people to a medical risk (experimental vaccine) for no scientific benefit.

(Needless to say, running an invalid vaccine trial also has very bad consequences: it would delay the actual deployment of a working vaccine to the general public, resulting in millions of unnecessary person-hours of potential virus exposure.)
