This is comparable to datacenters in space. We have no idea whether:

a) it is possible to construct such a scanner

b) the results of a scan would be able to diagnose anything

c) the false-positive rate would be low enough to make this useful

But it is probably very good as a source of speculation to hype the valuation of the company, because iff the above issues are solved, then this could be very valuable.

If any company can put profitable data centers in space, it will be SpaceX. But I doubt that any company can. The difficulties of the physics and engineering of cooling seem like they will always outweigh the advantages of keeping your data center on Earth.

I am annoyed by the insistence that the value of this company comes from something that no one has been able to show is possible yet without multiplying it by the obvious risk factor. And they seem to have got other companies like Alphabet[1] and Anthropic to publicize the idea, to give it more credibility.

I do not want my pension to automatically buy shares at $1T, but it looks like it will have no choice.

Engineers at google have publically stated that the models are too big and are far from their potencial

Can you link to a source?

Talking in terms of "carbon" is misleading. Methane is much more potent than CO2. I don't know why you think methane is broken down at the same rate as it is added.

- Cattle release methane

- Forests are burnt to make room for crops/grazing

- Fertilizer for crops for cattle produces nitrous oxide

I do not claim this adds up to 60%, but to suggest it is zero is incorrect.

re 2: special relativity is not general relativity - large elements will not provide testable predictions for a theory of everything that combines general relativity and quantum mechanics.

re: "GR environments (such as geostationary satellites)" - a geostationary orbit (or any orbit) is not an environment to test the interaction of GR and QM - it is a place to test GR on its own, as geostationary satellites have done. In order to test a theory of everything, the gravity needs to be strong enough to not be negligible in comparison to quantum effects, i.e. black holes, neutron stars etc. your example (1) is therefore a much better answer than (2)

SQLite's File Format 11 months ago

poorly designed storage layer, poorly designed column formats, and a terrible SQL implementation

Is this opinion shared by others?

That 100x zoom looks a bit... sloppy...

The car has one wing mirror and the rear tire is wider than the front. Edit: this might be real, see child comments.

Is there someone who knows more about cars who can confirm that this is in fact, not real?

For instance, when you're calling an airline, it can automatically find your flight details from your email and display it during your phone call.

Is this really the best example usecase they can think of? How often does an individual call an airline? I'm sure in aggregate they get a lot of calls, but I don't think I've ever had to.

It just seems really weird that this is the top example of on-device AI. The other examples mentioned, like "finding the right photos to share with a friend", seem more relatable.

I don't know what Sabine would spend $40B on instead, but intuitively that seems like it could buy a lot of research in a lot of areas, rather than picking particle physics.

And it doesn't have to be physics, it could be cancer research, or not even research: each country involved could upgrade their sewage system instead.

But Sabine doesn't have to have all the answers to be right to point out that there's an enormous conflict of interest if you ask particle physicists whether they'd like $40B. Of course they'll say yes.

[1] Sabine says "It’s a two-phase project, the first one, called the FCC-ee would collide electrons and specifically measure the properties of the Higgs boson." approximately 20 seconds into the video.

It's unfair to merely critique the headline. If you do not wish to watch the video, here is a transcript: https://www.youtube-transcript.io/videos/elvEcWc7U7c

"This is very important work." is just an opinion.

"The more precise you nail down these uncertainties, the more theorists can do to verify their work, allowing the experimentalists to know where to look for new stuff, if any." Sabine's point is that there are countless theories and parameters that can be changed to fit any measurement. New results will eliminate some, but it will not reduce the total number of possible theories, as others will be constructed to fit the results without having any reason to think one is more true than another.

But one of her points is that many of the jobs of current physicists depend on the status quo. That seems almost tautological. She then alleges that that clouds their judgement on the best use of research funding.

I'm sure that if you asked a range of physicists if _their_ area of research should receive more funding instead of the FCC, you would see less support for the FCC.

So we, as outsiders, are stuck not knowing what to believe - and ultimately an outsider, a politician, must make the decision for funding.

years at a time

I don't think any single crew deployment reaches a year.

more dangerous and isolated circumstances

I think Mars is massively more dangerous and isolated. A submarine can plausibly return to port or surface to breathable air. There is no such option on Mars. Nuclear submarines are much larger than spacecraft and have much more room for comfort options. They have a much larger crew, and the knowledge that this happens all the time from many nations must be of some comfort.

Your choice of numbers is very odd - even though you mention that you can adjust them for your own circumstances, the starting point is unrealistic.

- Very few people earn $1.5M/year

- Saving 20% implies that you're spending ~$1M/year while working, so $150k/year in retirement would not be appealing

Did the LLM pick the numbers for you?
