Well, that would eliminate all suffering without replacing it with more suffering - it would be an instant painless death for all life - so it can’t be all had.

The DNS system is inherently centralised, so is IP address assignment. In both cases you have to got through a centralised agency or their intermediaries.

Sure, those phrases have been used against Jews, I’m not denying that. I’m also not denying that the Republican party is wrong in most things. But those phrases don’t actually say who is behind the curtain, or puppeting billionaires. They could be implicating anyone.

Can’t disagree there! I do wonder how you think such a society might arise though. How do we get from how we are now to a fair society where everyone benefits equally from advances in automation?

The placebo affect is what the comment is describing, it’s not an additional effect. And it’s more a product of your cognition - your expectations, than the more biological effect of an actual drug on brain chemistry.

Why shouldn’t artists have to find other work if their primary work is unnecessary? Not saying AI is good enough to replace them yet, but when it is, why shouldn’t it? Free people’s time for more worthwhile endeavours, no point being payed to do something that can be automated - besides for niche circumstances, such as artisans. But most artists today are employed doing soul-breaking tasks like graphic design for ads, and if AI can free people from that, I’d be all for it. Why wouldn’t you?

What about when people paste copypastas, share memes, or reference age old arguments? The very culture of internet comments seems to be opposed to copyright.

Are you saying Microsoft CoPilot didn’t respect copyleft licences? How are they not getting totally sued for something obviously illegal? Or is it only when copyright violations harm big companies that people get sued?

Yeah, but it doesn’t look very good. Not compared to something like Jerboa or any other native Android app made with Material You.

Jerboa’s instance blocking is actually one of the few ways it works better than Voyager, letting you block instances directly from the post dropdown rather than needing to go two menus deep into settings.
- Comment on Which is the best Lemmy app for mobile? 2 weeks ago:
Voyager for a good app that has an iOS look. Jerboa uses Material design, if you prefer that, but to doesn’t work as well.

Well, tradition is opposed to the scientific method, which advocates constantly reassessing what you think you know, if that’s what you meant.

Indeed, it can’t be a reference frame, as even if it’s not accelerated, it’s everywhere, so it doesn’t have a position or orientation.

- Comment on NHS charter to stress biological sex when placing patients in wards 2 weeks ago:
Why split things like bathrooms or hospital wards by sex or gender anyway? Any solution that validates trans people while still separating genders is only going to be a bandage solution at best, as it doesn’t solve the underlying issue of sexism “I can’t be in the same room as someone of another sex/gender, that would be terrible!” Like what? Are we trying to accommodate religious idiots instead of trans people or something?

The can’t be bigger today however, as they are limited by the oxygen concentration in the air. In the past, there was a higher percentage of oxygen in the atmosphere, so so insects could be bigger and thus have a lower surface area to volume ratio, because the air they did intake through their exoskeleton had more oxygen, so it was possible to spread oxygen throughout their body. But when the oxygen level dropped, they had to become smaller so that their surface area to volume ratio dropped, and the oxygen they intook could go further.
More detail
During the Carboniferous period, which lasted from about 359 to 299 million years ago, giant dragonflies and huge cockroaches were common. These prehistoric insects grew to impressive sizes, and one of the leading theories behind their gigantism is the abundance of oxygen in the atmosphere at that time. Here’s how it worked: 1. High Oxygen Levels: The rise of vast lowland swamp forests during the Carboniferous period led to atmospheric oxygen levels of around 30 percent—close to 50 percent higher than current levels. This rich oxygen environment allowed adult bugs to grow to ever larger sizes while still meeting their energy needs. 2. Larval Perspective: However, the new study suggests that it’s not just because oxygen affected the adults. Oxygen had a bigger effect on larvae. Insects like dragonflies and stoneflies have a larval stage where they live in water before becoming terrestrial adults. Larvae typically absorb oxygen directly through their skin, so they have little control over how much gas they take in. When oxygen levels were high, this passive absorption could lead to oxygen poisoning. To decrease this risk, growing bigger was advantageous because large larvae would absorb lower percentages of oxygen relative to their body sizes. 3. Regulating Oxygen Intake: Adult insects, on the other hand, can regulate their oxygen intake. They have valve-like holes called spiracles that allow them to adjust the amount of oxygen they absorb. While oxygen is crucial for life, it can be poisonous in large quantities. Humans exposed to excess oxygen can suffer cell damage, vision problems, difficulty breathing, nausea, and convulsions. Ancient insect larvae likely faced similar risks when oxygen levels were exceptionally high. 4. Dragonflies and Cockroaches: Not all insects responded the same way. For instance, dragonflies grew faster into bigger adults in an oxygen-rich environment (hyperoxia), while cockroaches grew slower and did not become larger adults. Overall, ten out of twelve kinds of insects studied decreased in size in lower oxygen atmospheres. The hollow tracheal tubes insects use to breathe played a crucial role in these responses. 5. Fossil Proxies: Understanding how modern insects respond to varying oxygen levels could help us use fossilized insects as proxies for ancient oxygen levels. By studying the plasticity of modern insects raised in different oxygen concentrations, researchers gain insights into the evolution of insects and the impact of oxygen on their size and growth.

The CMB is everywhere, and anywhere in the universe it’s the same distance from a hypothetical observer. I fail to see how you can use it as an absolute reference frame.
