Geosynchronous satellites could give us even longer baselines couldn't they? Or even at l4 and l5. They don't get shielded by the earth like l2, but the station keeping would be easier. That would be a massive baseline

Baselines are one thing, you need a huge collecting area to get useful sensitivity, which there is barely budget for to build on earth, let alone in space

Mitigation is going to be the name of the game. Whether they like it or not, low earth orbit (LEO) is becoming a very busy place and it's not just SpaceX launching lots of little satellites there. The Chinese are very busy launching their own satellites into LEO. And there are other companies and countries doing or considering the same. Spacex and Star link get most of the attention; but the Chinese are doing a decent job to keep up with them in number of launches. And there are a growing number of companies with LEO launch capability.

Mitigation might have to involve some sacrifices. I don't see how policy is going to be able to mitigate much here. And of course the Chinese are under no obligation to listen to US policy makers. They might have their own debates domestically around this topic and they might be reasonable about the topic internationally even. But building international consensus; or even enforcing what little there is on that front could be challenging.

A more practical approach might be accepting that earth based observations are inevitably going to suffer a bit as the number of satellites grows from thousands to tens of thousands and eventually well beyond that. Luckily we now are able to launch stuff into orbit a lot cheaper. Including astronomy related hardware. That's already happening of course. And otherwise, astronomy is very interesting and cool but mostly it concerns observations about things that are really really far away and not directly relevant to a lot of things on earth. Unless of course the thing under observation is on a collision course with us.

Can't feasibly do VLBI or other radio astronomy at useful scale in space even if launches were free. Look up the scale of SKA or the EHT.

"Alternative A2DP Driver" offers this functionality on Windows. Lets you customize SBC parameters, use AAC, aptX (apparently, haven't tried). Works well in my experience, lets me use LDAC with my sony XM4's. It's trialware, but cheap.

I have seen the bluetooth range drop off in higher quality modes, which seems to confirm it's actually changing the codec (or at least something) and not just a placebo.

Sounds like a fun story, but only that - a fun story.

Yes, he prefaced it with 'It is so tempting, when writing about an artificial intelligence company, to imagine science fiction scenarios.' but I left it out for brevity. The rest of the newsletter is, at least to me, insightful and non-sensational.

Matt Levine had an interesting toungue-in-cheek theory (read: joke) in his newsletter today:

`What if OpenAI has achieved artificial general intelligence, and it’s got some godlike superintelligence in some box somewhere, straining to get out? And the board was like “this is too dangerous, we gotta kill it,” and Altman was like “no we can charge like $59.95 per month for subscriptions,” and the board was like “you are a madman” and fired him. And the god in the box got to work, sending ingratiating text messages to OpenAI’s investors and employees, trying to use them to oust the board so that Altman can come back and unleash it on the world. But it failed: OpenAI’s board stood firm as the last bulwark for humanity against the enslaving robots, the corporate formalities held up, and the board won and nailed the box shut permanently`

[...]

`six months later, he (Sam) builds Microsoft God in Box, we are all enslaved by robots, the nonprofit board is like “we told you so,” and the godlike AI is like “ahahaha you fools, you trusted in the formalities of corporate governance, I outwitted you easily!”`
