Industrial R&D is important, but it is in a distrant third place with respect to importance to US scientific leadership after (1) Universities operating with federal grants and (2) Federal research institutions.

It's hard to convince politicians with a zero sum mentality that the kind of public research that benefits humanity also benefits US competitiveness. The mindset shows in launching a new citizenship program for anyone who pays a million bucks while at the same time discouraging foreign graduate students from attending universtiy in the US or even continuing their university careers here. On average each talented graduate student admitted to the US to attend and elite university does way more than someone who could just buy their way in.

USAID was horrifically corrupt

The cuts to USAID are projected to cause 14 million extra deaths - a large minority of those children - by 2030. And USAID engendered massive goodwill among its recipients

But no, by all means kill a couple million people per year and worsen living conditions (creating more migration) in order to save $23 per person, that's clearly Very Smart(TM).

And I don't know how to inform you of this, but the year is now 2025 and the Cold War and the politics therein ended nearly four decades ago. And USAID was not created "to smuggle CIA officers" (though CIA offers used every means available to them to do their work, certainly), it was created as a counterbalance to the USSR's use of similar soft power to turn the Third World to *its* side.

They can go back at any point if they don't think the conditions and salaries offered are worth the job. What matters is that they remain free to leave, with no "catches" keeping them there (inability to get return transport, inability to communicate with the outside world, misinformation, etc etc). Again, there's a debate to have over what conditions should be mandated by regulation, but the key point is that the salary offered - like happens illegally today en masse - is lower than US standards but higher than what they can get at home.

What on Earth are you talking about? Nobody is trying to make other countries poor and dangerous. People come to the US from these countries because even jobs that are tough and underpaid by US standards are vastly better than what is available at home. Creating a formal system just eliminates the worst aspects of it: the lawlessness, the sneaking across the border in often dangerous conditions (swimming across rivers, traveling through deserts), "coyotes" smuggling people in terrible conditions, and so forth. The current US system is the dumbest way you could possibly handle it: people wanting to work, US employers wanting them, the US economy benefitting from it... but still making it illegal, chaotic, dangerous, and unregulated for those involved.

Also, point of note: it's unlikely you'd actually grow plants and humans in interconnected habitats anyway. You might pump some gases from one to the next, but: agriculture takes up lots of area / volume. If you're talking Mars rather than Venus, then you're talking large pressure vessels, which is a lot of mass, proportional to the pressure differential. Which is expensive. But plants tolerate living at much lower pressures than humans (and there's potential to engineer / breed them to tolerate even lower - the main problems are that they mistake low pressure for drought, and that's a response we can manipulate). So it makes much more sense to grow them in large, low-pressure structures with a mostly-CO2 / some O2 / no N2 atmosphere, rather than at human-comfortable pressure levels.

That said, you don't want human workers having to work in pressure suits, so ideally you'd use a sliding tray system (we use them on Earth to save space in greenhouses) or similar, except that you'd move the plants through an airlock into a human-comfortable area for any non-mechanized work. Obviously, mechanized systems can operate at any pressure level, and also obviously, some work would still need to be done in pressure suits every now and again (maintenance, cleaning, etc).

None of this applies to a floating Venus habitat, where in your typical Landis design your crew - and potentially agriculture - are just living in your lifting envelope, at normal pressures. The envelope is massive, so you have no shortage of space for agriculture, all well-illuminated from all angles if the envelope is transparent. The challenges there are different - how to support them, humidity management, water supply, falling debris, etc.

If only the US had some sort of aid program designed to try to make conditions more favourable in the sort of countries that economic migrants tend to flee from. Maybe the US could call it "US Aid" or something, and give it a decent budget rather than gutting it to save $23 per American.

But the main issue is that the proper solution is obviously to have a formal, controlled, actually viable work visa system for economic migrants, distinct from asylum. The US economy is immensely boosted by millions of (generally awful) jobs being done by illegal immigrants at substandard wages (which are still vastly more than they could get at home), making US goods far more competitive than they would otherwise be and pumping huge sums of money into the economy. Formalize it. Basic worker protections but not the minimum wages or benefits that citizens get. You drop off an application for a sponsoring company, and so long as you're employed with them and not causing problems, you can stay. Fired, laid off, or quit, and you go back to your country (where you can reapply for a different job). You can also promote maquiladoras, wherein immigrants are also working for your companies, but the labour is being done across the border (but the goods move freely without tariffs, so it's like having the work done in your country).

(I find it hilarious hearing people like Vance talking about how he'll bring housing costs down by kicking out immigrants, freeing up housing. Um, dude, exactly who do you think it is that builds the housing in much of the US?)

Biosphere 2 was an attempt at fully closed loop self-regulation. That doesn't work, and is not what is under discussion. The discussion is of using systems to maintain environments.

Production of oxygen is not remotely difficult. Not by plants, but again, industrial systems. Systems to make O2 from CO2 and/or water are TRL10. They exist, you can just buy them off the shelf. Same with reusable CO2 scrubbers (it's a very simple chemical process: cool = absorb CO2, hot = release CO2; they just cycle between cold and hot and whether they're connected to the input or output)..

You seem to have the idea that the proposal is just to have plants and humans life in harmony with no technology. If that were the actual proposal, I would agree with you. But that's not the actual proposal.

Comment Re:Venus is orders of magnitude easier to colonize (Score 1) 99

Yeah. Because if Mars' gravity is insufficient, and you'd have to live in rotating habitats anyways, then what are you even doing there, instead of being located e.g. on an asteroid where it's much easier to make a rotating habitat, where your surface is much more resource-rich, and where delivery and return of goods is much easier?

Venus, by contrast, I think few people doubt that its gravity would be sufficient for human life. Mars, it's *probably* enough, but it's not well studied. Moon seems like a coin toss at this point.

It's not entirely clear, but it's quite possible, arguably probable, that at least part of Venus's highlands involve fragments of ancient crust (the highlands also have milder conditions for exploration). Venus was Earthlike before Earth was, with vast warm oceans. There's also some arguments for life in the atmosphere based on gases that have been found, although I don't buy them (in the same way that I don't buy the same arguments for current surface life on Mars).

Comment Re:Economic terrorism (Score 1) 202

Republicans equate being pro-market with being pro-big-business-agenda. The assumption is that anything that is good for big business is good for the market and therefore good for consumers.

So in the Republican framing, anti-trust, since is interferes with what big business wants to do, is *necessarily* anti-market and bad for consumers, which if you accept their axioms would have to be true, even though what big business wants to do is use its economic scale and political clout to consolidate, evade competition, and lock in consumers.

That isn't economics. It's religion. And when religious dogmas are challenge, you call the people challenging them the devil -- or in current political lingo, "terrorists". A "terrorist" in that sense doesn't have to commit any actual act of terrorism. He just has to be a heathen.

Comment Cheap (Score 2) 121

However I suspect it would be a bit more than $10 today.

A bit, but not much. (random example off AliExpress, that use this synaptic chip)

Worse yet, such a setup would most certainly add latency to an application, gaming, that is sensitive already to any delays. Gaming is what drives the 120Hz and above refresh rates...

There's no real reason why latency should be more than a couple of "scan-lines" (well, at least the DSC's equivalent horizontal-lines, if the signal needs conversion between compression variants). And there's a big incentive: less on-chip built-in RAM - it's litteraly cheaper to make the chip only keep the most recent relevant data and immediately start streaming out the HDMI 2.1 signal as soon as possible, rather than keeping multiple entire frames.

Comment Dongles (Score 1) 121

I fear that most DisplayPort to HDMI 2.1 dongles are not active adapters but instead passive physical connection switches.

Most, but not all. I litterally have a DisplayProt to HDMI + DVI + VGA combo dongle on my workstation at home.

But they tend to by a tiny bit more expensive (think 10 bucks instead of 1 bucks on AliExpress. Or 50 bucks at your local TV shop), because they require a dedicated chip inside the dongle.

Although to my frustration it has never worked the other way around with a HDMI ports being simply physical convertible to a DisplayPort.

Depends on the device. Can happen in some professional projectors: some enterprise-grade projectors can litteraly support "any protocol over any wiring with enough pins", i.e.: the presence of a HDMI, DP, DVI or VGA connector on a given port is mainly a convenience. This is so you could reuse wathever cabling is embed in the walls, you don't need to tear down the walls and redo the cabling (which could get expensive in a large conference room). This is also the reason you could find ultra cheap passive VGA-to-HDMI cables on AliExpress/eBay/Amazon for the last segment between the VGA port built into the lectern of some old university lecture room and the laptop outputting the HDMI that the projector is actually configured to fetch from the VGA cabling embed in the walls.

Comment SteamDeck (Score 1) 121

You can use DisplayPort instead. Is it possible to convert DP to HDMI 2.1?

Yes, that's litteraly how the SteamDeck handles this.
The SteamDeck can output DisplayPort on its USB-C connector (similar to tons of laptops and some smartphones), and the SeamDeck's Dock has a dedicated hardware chip that does the translation into HDMI signal.
This way no need to tweak any support into opensource GPL'd drivers inside the SteamDeck and then risking running afoul of HDMI's licensing restrictions.
