Seriously, the idea that we know all the practically important physics there is is the kind of thing only somebody who's never done science or engineering would believe.

You seem to be confusing "wanting to get rid of communists" with "wanting their countries to be poor and dangerous".

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.

This will be great for Haiku, FreeBSD, and OpenBSD installs, there's not the remotest possibility there'll be binaries for these. Not because the software couldn't be ported, but because the sorts of people politicians hire to write software would never be able to figure out the installer.

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.

I still can't get ChatGPT, Gemini, or Claude to write a decent story or do an engineering design beyond basic complexity. They're all improving, but they're best thought of as brain-storming aids rather than actual development tools.

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?)

It'd have to support full-text search by default. Mastodon, last I checked, was still in practice stuck with tags-only search that fails unless both the poster and searcher manage to correctly #GuessTheHashtag. I've read that Mastodon added in version 4.2.0, but I've never got it to work because it's not the default: the posting user has to deliberately seek out how to opt into full-text search before sending posts, and the administrator of the searcher's instance has to spend a lot more money for a much larger VPS with the RAM for Elasticsearch or OpenSearch.

"Refugee papers" OMG I'm dying here...

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.
