> "They're right to point out that laws like this are primarily motivated by government control of speech. On a recent Times article about the UK's Online Safety Act:"

Err, BlueSky is enthusiastically complying with that one (as you read by clicking through to their corporate statement),

> "We work with regulators around the world on child safety—for example, Bluesky follows the UK's Online Safety Act, where age checks are required only for specific content and features... Mississippi’s new law and the UK’s Online Safety Act (OSA) are very different. Bluesky follows the OSA in the UK. There, Bluesky is still accessible for everyone, age checks are required only for accessing certain content and features, and Bluesky does not know and does not track which UK users are under 18. Mississippi’s law, by contrast, would block everyone from accessing the site—teens and adults—unless they hand over sensitive information, and once they do, the law in Mississippi requires Bluesky to keep track of which users are children."

It's bold of them to attempt to shift the Overton Window in this way ("OSA is actually moderate and we should hold it up as an example of reasonableness to criticize other censorship laws against"). That happened fast.

I think this is weirdly cynical. BlueSky isn't in favor of OSA, they're saying that the Mississippi law is radically worse.

Well, while we're talking about anecdotes, my neighborhood in a poor Texas town also had a free tennis court. There were a couple more down the road. My in-laws suburb has walking trails end basketball courts.

If you live in a place with inexpensive land, tennis infrastructure is relatively cheap. If you live in a dense city where space is at a premium, that’s when it gets relatively expensive.

While I get the point... to be pedantic though, Napster (first gen), Gnutella and iPod were mostly download and listen offline experiences and not necessarily live streaming.

Another major difference, is we're near the limits to the approaches being taking for computing capability... most dialup connections, even on "56k" modems were still lucky to get 33.6kbps down and very common in the late 90's, where by the mid-2000's a lot of users had at least 512kbps-10mbps connections (where available) and even then a lot of people didn't see broadband until the 2010's.

that's at least a 15x improvement, where we are far less likely to see even a 3-5x improvement on computing power over the next decade and a half. That's also a lot of electricity to generate on an ageing infrastructure that barely meets current needs in most of the world... even harder on "green" options.

I moved to NYC in 1999 and got my first cable modem that year. This meant I could stream AAC audio from a jukebox server we maintained at AT&T Labs. So for my unusual case, streaming was a full-fledged reality I could touch back then. Ironically running a free service was easy, but figuring out how to get people (AKA the music industry) to let us charge for the service was impossible. All that extra time was just waiting for infrastructure upgrades to spread across a whole country to the point that there were enough customers that even the music industry couldn’t ignore the economics; none of the fundamental tech was missing. With LLMs I have access to a pretty robust set of models for about $20/mo (I’m assuming these aren’t 10x loss leaders?), plus pretty decent local models for the price of a GPU. What’s missing this time is that the nature of the “business” being offered is much more vague, plus the reliability isn’t quite there yet. But on the bright side, there’s no distributed infrastructure to build.

This is great long term for having cars that follow traffic laws since human drivers in NYC are awful (kill/injure pedestrians, bikers, and other street users all the time).

Not so great for getting cars out of NYC and pedestrianizing more of the city/moving towards more “low traffic neighborhoods” as I imagine Waymo and other similar companies are going to fight against these efforts.

Edit: Lots of people talking about human drivers taking advantage of self-driving cars being more cautious/timid. Good news is that once you have enough self-driving cars on the road, it probably slows down/calms other traffic (see related research on speed governors).

It just means that feral bikers will take over the roads ;)

It would be one thing if Bluesky were a no-politics, effortpost-only zone. It's not that though. In actuality, Bluesky is an echo chamber just like 2010s-era Twitter, but somehow even more strident.

Academics who insisting on their colleagues moving to Bluesky aren't deleting noise. That's a pretext. What these academics are really doing is trying to use their social power to enforce singular answers to questions that divide the public. They're tacitly asserting that nobody can be a legitimate intellectual and disagree with them on social issues having nothing to do with their field.

I'm not going to waste my time on people who can't tolerate divergent perspectives. X has plenty of tools to help people prune distractions from their timelines. This isn't a signal to noise ratio thing so much as a contamination taboo. Frazer would be proud. The problem these academics have with X isn't that it's noisy channel, but actually that it lets the wrong people participate.

These academics think they have a monopoly on knowledge production, but they don't. Close-mindedness bleeds from the social to the professional domain with terrifying speed. Censorship is anathema to discovery. When academics try to use ostracism to build echo chambers like Bluesky, they're only accelerating the ongoing divorce of academia and scholarship.

Bluesky isn't perfect, and I actually find it kind of annoying, but it's a "follow who you want" place. If your timeline is strident, that's because you followed people who are strident. The same isn't really true of Twitter, where even the "Following" timeline shows you algorithmically-recommended content and then boosts the replies of paying customers (AKA scammers.) To get the same feature from X, you need to do something complicated with "Lists", and it doesn't fix the reply ordering problem.

The rest of your comment tells me that you don't really spend a lot of time with scientists, but you do spend a lot of time developing your opinions from social media. I wish you could do the opposite! Academics are great and funny and sometimes wrong about social issues just like other people, but they also work on some of the coolest problems we have.

You’re posting this here on HN which is a curated social space that absolutely does not let you post annoying things that serve only to offend people and is good because it produces high signal/noise. Presumably you’re here because you appreciate that high quality discussion. Thats what Twitter used to be like for scientists, except that you also had access to smart people from industry and smart non-scientists as well and so “scientists in the academic bubble” had access to a huge number of perspectives. Now X is 4chan. 4chan is useful for its specific brand of content, it’s just not useful the way HN is or Twitter was.

BlueSky and Mastodon are as relevant and useful as Blogger.com; Threads meanwhile has leeched itself to Instagram and somehow existing.

There is no point in creating an account there, even the Elon Haters have gone back, they keep the BSky account as a backup.

Sad, but if you want to feel the global pulse (however weak) X/Twitter is still the place.

Also X/Twitter is an insane name.

matthewdgreen · 2 days ago
I have 140k followers and a strong incentive to go back to X. I do check in occasionally for the reasons you state, and it’s unusable and high-noise every time I do it. There was a golden age for science on Twitter and it’s over. On BlueSky I don’t get the huge engagement (and there’s too much politics) but I can blather on about cryptography and people are enthusiastic and I don’t get weird bluecheck crypto scammers in my replies.

Oh, like RealPlayer in the late 90's (buffering... buffering...)
matthewdgreen · 2 days ago
RealPlayer in the late 90s turned into (working) Napster, Gnutella and then the iPod in 2001, Podcasts (without the name) immediately after, with the name in 2004, Pandora in 2005, Spotify in 2008. So a decade from crummy idea to the companies we’re familiar with today, but slowed down by tremendous need for new (distributed) broadband infrastructure and complicated by IP arrangements. I guess 10 years seems like a long time from the front end, but looking back it’s nothing. Don’t go buying yourself a Tower Records.

I have an overwhelming feeling that what we're trying to do here is "Netflix over DialUp."

We're clearly seeing what AI will eventually be able to do, just like many VOD, smartphone and grocery delivery companies of the 90s did with the internet. The groundwork has been laid, and it's not too hard to see the shape of things to come.

This tech, however, is still far too immature for a lot of use cases. There's enough of it available that things feel like they ought to work, but we aren't quite there yet. It's not quite useless, there's a lot you can do with AI already, but a lot of use cases that are obvious not only in retrospect will only be possible once it matures.

As someone who was a customer of Netflix from the dialup to broadband world, I can tell you that this stuff happens much faster than you expect. With AI we're clearly in the "it really works, but there are kinks and scaling problems" of, say, streaming video in 2001 -- whereas I think you mean to indicate we're trying to do Netflix back in the 1980s where the tech for widespread broadband was just fundamentally not available.
