Wow I never thought about it that way. Fascinating!

> south australia is somewhere around 15-25% renewables from what i can see
More like 70% (slightly under that), source. 25% (well, 29% as of 2021) is closer to the figure for the whole of Australia.

I think I actually did. I applaud your idealistic passion, but its met with cold chaotic reality of our society. We could go 100% renewable in a decade or two. There is no doubt about that. Just like we could end wars forever. We just dont have the motivation to do so. Its not just few people. Its all of us.
What we can do and what we are doing is using resources we have available to make the transition possible bit by bit. The renewables are going to win, its almost inevitable. But we have to make sure we are ready for it. An example of what we are doing to rely less on the dirty power plants is we share them with other countries. We are maximizing the utility of those remaining power plants. This is happening right now.

Generate actual consciousness or an illusion of consciousness? The issue is the definition of consciousness itself and there are multiple philosophical definitions and thoughts on consciousness. Even if a machine appears to have conscious thought it doesn't mean that machine is actually conscious. I for example believe I'm conscious because I have awareness of my surroundings and inner reflection of my being. Of course that is my own belief in my experience. However a person could believe they are the only conscious being in the Universe because they only experience their own Intrinsic consciousness, of which they assume is the same as other humans.
So whether a machine has actual consciousness in the way humans experience consciousness there doesn't exist a test. We can perform experiments/tests to see if the machine is representing consciousness in the same way we do but that doesn't mean the machine is conscious.

Maybe you don't want to understand. People who say they can never understand someone usually just don't even try to understand because its way easier to say i just don't understand, plus trying to understand someone else's opinion which disagrees with yours is just too mentally uncomfortable, that also adds to the biased "I'll never understand"

You mean for mind uploading? Honestly, probably not. I doubt we'll have entirely solved the HPOC by the time we figure out mind uploading technology.
We will figure out what sorts of algorithms generate consciousness, even if we don't entirely understand why. That will probably be achieved before we master mind uploading, or at least not long after.

We don't have insurance companies in BC, so... Sucks to be american I guess :(

Why would they do that? Even now, most private health insurance policies cover palliative and/or hospice care. I'm not sure how the ability to predict mortality with better precision would change that.

Well you convinced me! I humbly apologize for being so very wrong about everything. Thanks for correcting me, sir!

this is a fascinating way to look at it, i never heard of this before. can you say more about this? would love to see what government agencies, corporations, academic say about this

I'll never understand why someone would want to know when they're going to die.

Using Ad hominems isn't the best argument. Do some research.

I worry that with 80% accuracy, it may be condemning the remaining 20% to an unnecessary death.

UPS systems are highly efficient when powering a designated load. The problem is the grid, it's far from a designated load. This is because the grid power is highly variable, and the UPS system must constantly adjust its output voltage and frequency to match it. This can result in additional losses and reduced efficiency. Additionally, the reactive power necessary to push out KVARs can also contribute to losses, especially when there are extra reactive elements in the mix.
Another challenge that can affect the efficiency of grid-connected UPS systems is the overall power demand on the grid. If the UPS system is connected to a heavily loaded grid, it may not be able to provide sufficient power to its designated load, which can result in decreased efficiency or even failure of the UPS system.
I'm not saying it's impossible, but with our current grid demands, it's unrealistic to think that we can power the world by solar and wind alone. That's what I'm saying.

Speaking to the future one could also argue that there will be fusion someday and because of its energy density it will be economically much cheaper than any other form of power generation.
Helion Energy is already 95% net electric and their upcoming 7th generation reactor should be slightly net positive, if all goes well in 2024 then commercialization will proceed. They have estimated they could initially produce 20 50W reactors a year.
Exciting times

>As I said, and as you apparently missed.
You didnt say.
>And the cost of not doing so is even more astronomical.
You arent wrong, but its such a childishly naive thing to say. You are pretending the world is united in shared vision and shared responsibility. Power engineering is extremely fractured.
Let me give you the basic problem. The power generation is a private sector. Corporation that build power plants do so for profit. They dont care about earth, health, politics and whatnot. How exactly do you plan on getting them to lose money on their investment? Same thing apply to commercial batteries that we would have to build tons to support renewable power plants. To stress my point further. You are not paying for power plants right now and you dont get a say.
To look at the "big picture" as you say, you had to take a few steps back and your head ended up in clouds. Let me try it. Crime cost us a lot. All the damages, the cost of justice system and police. And above all, the priceless cost of lives. But I think I have a solution. How about we all just stop committing crimes. Wow, that was easy. And its absolutely free. Hurray for the big picture!

I work in the power industry and gain nothing from lying, I just point out the energy hypocrisies when I see them. 🤷🏻♂️

Reply to Artificial intelligence could soon be widely used to detect breast cancer — and may be more effective than doctors at doing so, study says by Gari_305
From the article
>The ever-growing wave of artificial intelligence technology is continuing to expand into the field of medicine, as several clinics across the globe begin experimenting with AI to help doctors detect breast cancer.
>
>Hungary has been one of the largest and earliest adopters of the technology, as at least five hospitals or clinics that perform thousands of breast cancer scans per year have used AI programs since 2021, according to the New York Times. The success of using AI to detect cancer in the Hungarian clinics has inspired doctors in England, Scotland, and Finland to also experiment with the technology, per the Times.
>
>In a study published last year that charted an AI program's ability to identify breast cancer in 250,000 scans, the technology was found to be as effective, if not more so, than a human radiologist, and was also able to read scans more quickly overall.
>
>The study concluded that incorporating the technologies into the medical field could reduce the workload of radiologists by having an automated system that can provide a second opinion quickly and accurately.
