Right, it looks pretty catastrophic for some areas (eg South Korea) if it doesn’t stabilize. But I’m also skeptical of anything that extrapolates anything related to human behavior out 75 years.

This happens, but it's not representative. Interesting belief, it seems like it should be self-extinguishing, the cultures that don't believe this kind of thing will tend to take over over time.

Haha the “but” wasn’t meant as an excuse for the terseness. Am I wrong about the comment history? Might be biased.

I asked if anyone could rebut it. Normally I'd do the work myself, but I'm not very up to speed on this stuff and I wasn't in a good place to do a bunch of research, and someone who's been following it more closely could

by ericd 6mo ago
Relax, I was mostly asking whether someone else who already knew about this stuff could comment on its veracity. There’s obviously no obligation.

by ericd 6mo ago
Usually it’s on the person posting assertions to justify them, and looks like they’ve edited in a NYT link since then.

by ericd 6mo ago
Ah thanks, I think that was added after I commented.

That’s what I was doing, because I don’t think assertions like “CENTCOM is blind” should just sit out there without evidence.

by ericd 6mo ago
Did a quick search, didn’t see confirmation that they’re blind/that all radars had been knocked out. Was asking whether others who know more about this topic than me would confirm.

Traveling with kids on spring break, I don’t have time to read all war related news, and it tends to set off my propaganda account alarm when someone registers a new account to drop a bunch of assertions on such a politically divisive topic

Fact check on this brand new account?

Yeah, true, they have gotten pretty good at lobbying. Hoping they can beat the utility lobbies to really open up renewable energy development.

Thanks, I took a look, couple things - the inlet temp on the VR is 45 C, but that’s not the radiator operating temp, you can probably run those chips closer to 90-100 C. And they’re building custom silicon for this, presumably that’ll be on

One Vera Rubin rack costs $3-7M and eats something like 600 kw, so you’re probably looking at more like 800 racks for that 500 MW DC. $100k launch costs per rack doesn’t seem too terrible if that’s what it works out to. I’m sure there’s a m

I think you're understating the permitting problem - it's a major reason for the very large/rapid price hikes on power in the PJM region, and the populist backlash against data center construction, including moratoriums on DC

Yep, I tried it when it had the original logo, was using Altavista until then, it was immediately obvious that they were going to win.

Could you link to those serious analyses? The ones I've seen don't portray it as a total impossibility? Scott Manley did a runthrough that seemed reasonably positive on the possibility.

You left some GPT notes in the body, and it seemingly repeats the whole post again.

Absolutely. I wonder how many parents have been no contacted, SOs broken off with, friendships broken because of the Reddit hivemind's attitude. Pretty sure it's doing a huge amount of societal damage.

Right, a mix of uncorrelated sources is much more resilient than 100% renewables. Of the cleantech industry people I listen to, none of them are advocating for 100% renewables, you need a mix for grid reliability. But renewables can take on

Most panels have a 25 year 80% production warranty. Unless they're planning on being out of business, they're not planning on them lasting <25 years. So their useful life is significantly longer than 30 years, unless we come up

It's aluminum, glass, silicon, and some conductive metal. Surely you all have those materials. And even if you don't make them yourselves, they aren't make and then burn like fossil fuels, they are durable infrastructure, you

For sure, but we need to stop hyperbolizing constantly, it's really not helpful.

It's possible to cross the border many times and not have this happen.

Well, also, LLM servers get much more efficient with request queue depth >1 - tokens per second per gpu are massively higher with 100 concurrents than 1 on eg vllm.

I saw a good quote recently, "you're not going to get 128 gigs of vram loose in a plastic bag for that much".

>This point also deserves special mention. Most green technologies (solar panels, electric cars) also require a bunch of cobalt. Again, the "badness" seems to depend on your a priori evaluation of what the cobalt is being used

heh man, I'm glad you got out of that easy, I definitely wore safety glasses 100% of the time after my experience. I think a lifetime of experience with dangerous wall outlets and harmless little 1.5V/9V DC cells teaches us the wr
