Okay, I agree. I think we can also agree that author is not a physicist and he just didn't think further. To me, the comparison can be understood. If he reads the comment he should correct the error.

2. It's a good analogy. Waterfall are falling because of gravitational potential energy, just like an electron would fall when put in an electric field.

At constant height, a dam on the moon have less potential energy than an actual dam.

And gravity is a potential: https://en.wikipedia.org/wiki/Gravitational_potential "It is analogous to the electric potential with mass playing the role of charge."

Hey, at least you'll be able to add that exterminated tigre specie in your postcard from your last adventure trip. And more water to that river, with some greener trees etc.

All of that without leaving your home ofc.

To me, the article just ask "Is it possible to simulate living organism features?" and say a small yes by saying "Simulations like these show how computation can produce lifelike behavior across scales".

I'm not expert to judge the result of "drawing a missing hand by using neural network on each pixels"(if it's what it's done? Again not an expert).

The title should definitely be "Is it possible to simulate living organism?" given the last sentence is "Simulations like these show how computation can produce lifelike behavior across scales".

Nothing about life is discussed here, it's not even defined once.

New comment by logtempo in "Drones Are Key to Winning Wars Now. The U.S. Makes Hardly Any"

Because low cost drones have been used since the beginning of the war in Ukraine, they are trained to use them. Also the quantity used is way higher than in other conflicts, lowering the price is more important.

There is also a need in adaptability. Delivering parts that meets a specific demand at a specific time is where 3D printing and diy drones shine and it's important in Ukraine frontline.

There is also a system in the way Ukraine is doing war that favorise diy drone. Basically, each units have a budget and you get more if your unit kill Russian soldiers/equipment. This in return give you access to more advanced drones.

I think today the drones are quite well equipped and the diy versions are less present.

It's a paper done by a phd, so it's part of a larger study that is probably more interesting than this paper.https://etheses.dur.ac.uk/15828/ (I'm not the author).

But the results and use cases seems to be legit to me. Agin, I'm not an expert on computer science and quantum physics.

New comment by logtempo in "Can I ethically use LLMs?"

logtempo — Wed, 19 Feb 2025 21:21:49 +0000

but you can't delete people? That's actually the big problem that need to be addressed imo. It happen now (or later) with llm, but in the past it have been a problem with industrialization (big unemployment of workers) and then globalization (unemployment of more local workers).

If it's not addreased correctly, llm won't be a progress for humanity.

But if you want to compare it "technically", maybe it's better to look at computer usage now vs with llm maybe (how many google request, sim failed, screen on etc.)

I think the claim is more about people's consistency in their choice. "If you care so much, start to [insert any environmental friendly acivity] and then we can discuss about LLM environmental impact".

Which is stupid.

You can put, for the same price, almost 20 fleascope in a classroom instead of one profeasional one.

I think it does have its place even today.

Your comment make sense only if you replace AI by LLM. The use of AI algo is usefull for many cases outside natural language processig problem and well before the "LLM revolution".

It's a threat to many workers imo, just like autonomous machine were to the workers during the industry revolution, and later with the factories moving to China. Many people suffered from unemployment and the solution so far have been solved by creating new needs and new jobs, as well as policies such as social security.

But with the externalization of intelectual work (which happen without IA, for ex. India tech) I wonder if such solution is possible.

agressive marketing to go viral and get subscriptions fast (it means easy paperwork and possibility to import your profile from linkedin), and focus on niche or specific jobs thematic where people know how convenient are simple tools.

We're talking about childrens that have between 11-18 years old.

I'm also not saying that teachers could ask nicely and then do nothing if the rule is broken. Actually, one could ask students to either put their phones in their bag or in a "safe phone-box", and still seize the phone if it's used.

Bringing awarness is important, when it comes to fighting addiction.

I guess "black hole awaken" is a more attractive headline than "black hole fart" !

It's really cool to see that we have so much instruments, we can actually monitor (a very small part) of the universe activity.

To me, the necessity to have a banning "law" is a sign of failure. We should teach children the why and how, incentive them to put, by themselves, their phone in a lockbox and eventually consider them as growing adult and not irresponsible childs.
