a key thing about vought — and all of these guys — is that they have a totally top down and hierarchical vision of the world. they believe that the cultural changes they hate can be turned off by destroying the federal government because they can’t imagine that they emerged bottom-up in society

Thomas Zimmer @thomaszimmer.bsky.social · 10h

What he’s railing against is a profound shift in culture, status… He’s obsessed with the idea that America is controlled by a leftist “ruling elite” - but “elite” isn’t defined socio-economically or by political power, it means something like: Getting to define “real America” and who gets to belong.

I conclude with some grim thoughts. Still, at least in the US and Israel, things haven't progressed to the point I describe here. They could, because no democracy is safe from collapse, but there's still a ways to go as Hirschman teaches us. And so we think, argue, and do politics. 26/26

Reading the Cuttlefish 2 paper and I really admire the clarity and simplicity of the introduction. Makes me understand a few things in new, different, and productive ways. Lovely.

Scalable, ultra-fast, and low-memory construction of compacted de Bruijn graphs with Cuttlefish 2 - Genome Biology

The de Bruijn graph is a key data structure in modern computational genomics, and construction of its compacted variant resides upstream of many genomic analyses. As the quantity of genomic data grows rapidly, this often forms a computational bottleneck. We present Cuttlefish 2, significantly advancing the state-of-the-art for this problem. On a commodity server, it reduces the graph construction time for 661K bacterial genomes, of size 2.58Tbp, from 4.5 days to 17–23 h; and it constructs the graph for 1.52Tbp white spruce reads in approximately 10 h, while the closest competitor requires 54–58 h, using considerably more memory.

I was already a hard AI-skeptic but this cements my long suspicion that there is no feasible path to anything close to return on invested capital for these data centers. Tech would need 15 to 25 times current AI revenues within the next 2-3 years just to break even. Not financially viable.

"I clearly hit a nerve in the industry, when judging by the number of individuals who reached out to chat," he wrote in an followup blog post. "In total, l've spoken with over two-dozen rather senior people in the datacenter universe, and there was an interesting and overriding theme to our conversations: no one understands how the financial math is supposed to work. They are as baffled as I am, and they do this for a living."
Kupperman's original skepticism was built on a guess that the components in an average Al data center would take ten years to depreciate, requiring costly replacements. That was bad enough: "I don't see how there can ever be any return on investment given the current math," he wrote at the time.
But ten years, he now understands, is way too generous.
" had previously assumed a 10-year depreciation curve, which I now recognize as quite unrealistic based upon the speed with which Al datacenter technology is advancing," Kupperman wrote. "Based on my conversations over the past month, the physical data centers last for three to ten years, at most."
In his previous analysis, Kupperman assumed it would take the tech industry $160 billion of revenue to break even on data center spending in 2025 alone. And that's assuming an incredibly generous 25 percent gross margin - not to mention the fact that the industry's actual Al revenue is closer to $20 billion annually, as the investment manager noted in his previous blog.

"In reality, the industry probably needs a revenue range that is closer to the $320 billion to $480 billion range, just to break even on the capex to be spent this year," Kupperman posited in his updated essay. "No wonder my new contacts in the industry shoulder a heavy burden - heavier than I could ever imagine. They know the truth."
Kupperman called that gulf between tech industry spending and actual revenue in 2025 "astonishing."
However, it doesn't even begin to scratch the surface. For example, how does it all shake out when we account for 2026, when hundreds of new data centers are expected to pop up?
"Adding the two years together, and using the math from my prior post, you'd need approximately $1 trillion in revenue to hit break even, and many trillions more to earn an acceptable return on this spend," he writes.
"If the economics don't work, doing it at massive scale doesn't make the economics work any better
- it just takes an industry crisis and makes it into a national economic crisis," he concludes.
Overall, the pessimists broadly agree: it's no longer a matter of if Al is massively overhyped, but when the whole thing comes crashing down.

Here is a PDF of chapter 17 - it's just 3 pages and will fill you with hope and optimism, or so I've been told share.eva.mpg.de/index.php/s/...

Statistics courses and books—this one included—tend to resemble horoscopes. There
are two senses to this resemblance. First, in order to remain plausibly correct, they must
remain tremendously vague. This is because the targets of the advice, for both horoscopes
and statistical advice, are diverse. But only the most general advice applies to all cases. A
horoscope uses only the basic facts of birth to forecast life events, and a textbook statistical
guide uses only the basic facts of measurement and design to dictate a model. It is easy to do
better, once more detail is available. In the case of statistical analysis, it is typically only the
scientist who can provide that detail, not the statistician.242
Second, there are strong incentives for both astrologers and statisticians to exaggerate
the power and importance of their advice. No one likes an astrologer who forecasts doom,
and few want a statistician who admits the answers as desired are not in the data as collected.
Scientists desire results, and they will buy and attend to statisticians and statistical procedures
that promise them. What we end up with is too often horoscopic: vague and optimistic, but
still claiming critical importance

A master class from MIT in responding to authoritarian overreach:

Your “premise … is inconsistent with our core belief that scientific funding should be based on scientific merit alone.
… America’s leadership in science & innovation depends on independent thinking & open competition for excellence.

Dear Madam Secretary,
I write in response to your letter of October 1, inviting MIT to review a "Compact for Academic Excellence in Higher Education." I acknowledge the vital importance of these matters.
I appreciated the chance to meet with you earlier this year to discuss the priorities we share for American higher education.
As we discussed, the Institute's mission of service to the nation directs us to advance knowledge, educate students and bring knowledge to bear on the world's great challenges.
We do that in line with a clear set of values, with excellence above all. Some practical examples:
• MIT prides itself on rewarding merit. Students, faculty and staff succeed here based on the strength of their talent, ideas and hard work. For instance, the Institute was the first to reinstate the SAT/ACT requirement after the pandemic. And MIT has never had legacy preferences in admissions.
• MIT opens its doors to the most talented students regardless of their family's finances. Admissions are need-blind. Incoming undergraduates whose families earn less than $200,000 a year pay no tuition. Nearly 88% of our last graduating class left MIT with no debt for their education. We make a wealth of free courses and low-cost certificates available to any American with an internet connection. Of the undergraduate degrees we award, 94% are in STEM fields. And in service to the nation, we cap enrollment of international undergraduates at roughly 10%.

source:
https://orgchart.mit.edu/letters/regarding-compact

• We value free expression, as clearly described in the MIT Statement on Freedom of Expression and Academic Freedom. We must hear facts and opinions we don't like - and engage respectfully with those with whom we disagree.
These values and other MIT practices meet or exceed many standards outlined in the document you sent. We freely choose these values because they're right, and we live by them because they support our mission - work of immense value to the prosperity, competitiveness, health and security of the United States. And of course, MIT abides by the law.
The document also includes principles with which we disagree, including those that would restrict freedom of expression and our independence as an institution. And fundamentally, the premise of the document is inconsistent with our core belief that scientific funding should be based on scientific merit alone.
In our view, America's leadership in science and innovation depends on independent thinking and open competition for excellence. In that free marketplace of ideas, the people of MIT gladly compete with the very best, without preferences. Therefore, with respect, we cannot support the proposed approach to addressing the issues facing higher education.
As you know, MIT's record of service to the nation is long and enduring. Eight decades ago, MIT leaders helped invent a scientific partnership between America's research universities and the U.S. government that has delivered extraordinary benefits for the American people. We continue to believe in the power of this partnership to serve the nation.
Sincerely,
Sally Kornbluth

From some of the reactions, I was right to assume it would be hard for people to appreciate the significance. This is not an “of course, two Nobel laureates” case. They’re huge field builders, Esther being still quite young. The kind of people who will attract many others, including young scholars.

It might be hard to convey to people outside economics just how seismic this is. The Trump effect has most certainly arrived to US academia.

I completed a PhD in Physics at MIT in '03. Even when the intensity seemed to be off-scale, there was one piece that I never doubted: the place had integrity, purpose, and passion.

It's clear the culture and drive of MIT remains.

MIT says no to the compact.

Question for the hive mind: Is this less or more likely if reviews and rebuttal are public?

Rebuttals currently aim primarily to sway one person (the editor). But if they are increasingly context for readers to judge the merits of criticism (eLife-type process), will they differ?

Elisa Fadda @elisafadda.bsky.social · 2d

What I abhor is the swamp of text in rebuttal (pages and pages on nothing) that does not address my query, but goes endlessly around it, to go to why 'I didn't do this because I can't care less about checking, about making my science accurate as I possibly can' 3/n
