With debt it is easy to determine that you are underwater and are going to be unable to make your payments in the future. Basic arithmetic really.

With climate the same is roughly true, but the models have a wider range of possible outcomes the further you go out. Still, it is not difficult to find some thresholds where the costs ramp up or thresholds we cannot not come back from with current technology.

America operates the most expensive illiteracy program in the world.

What if the machine says it in a nice way?

After the crash, they'll have to do even more layoffs.

Terran life is voracious and competitive and the result of 3-4 billions of years where only the winners get to carry on to the next generation. The life that evolved here on Earth is far more likely to destroy other planetary ecosystems than the other way around.

Obviously, precautions are warranted as we are dealing with something unknown. As you could end up with some annoying consequences like space mold eating your hatch seals. But as for some alien life showing up on Earth and taking over? If it's possible at all the probability is incredibly low, based on our understanding of life and evolution. Good luck to the martian lichen trying to pry native species out of their habitat.

And we have already traded rocks with other planets. And we've shown that some forms of life can live dormant in space for a very long time. If there is life on Mars, it is possible it's already been to Earth, and was immediately gobbled up.

Because consumers keep buying HDMI, even though it sucks.

I used to certify HDMI equipment, and the standards for HDMI were always there to protect IP rights even if it made the devices less reliable and harder to use. End-users just know that sometimes when they bought a new Blu-ray player or settop streamer that it didn't want to work at full resolution with their TV or their A/V switch or the various incompatibilities that exist between revisions.

At least in the current climate (and quite possibly indefinitely; depending on how prudent their investments are and whether they have any uncontrollably expensive hobby) there's not really any reason for the 'AI' guys to take such a servile attitude.

If you actually need the job, or are invested in the company's mission for some reason, it's a good idea to care at least slightly about how your paycheck doesn't bounce; but that's not really the position these guys are in. Exceptionally in-demand skillset and reputation; existing net worth almost certainly already enough to at least keep them comfortable indefinitely if they feel like quitting the rat race or get fired. Why settle for doing sordid adtech if you think that, best case, your boss in the sort of dumbass who would lose billions of dollars on the idea that Second Life would totally have the GDP of western europe, because reasons, and you can keep him paying you a handsome salary and providing you with the GPU compute time and dubiously sourced datasets that you find personally interesting; and worst case, if you lose the fight, you'll just be told to go sling ads, not fired and blacklisted.

Facebook isn't running a charity; but neither are these guys. Why wouldn't they try to take what they can get? Especially when the actually-profitable business units are fat enough that there's plenty of room for boondoggles, so long as you can sell them, rather than there being fairly tight constraints on how much you can waste before the company starts bleeding out.

It would honestly be more surprising if they signed up with facebook out of a genuine willingness to do adtech swill and sordid 'engagement' hacking; rather than on the assumption that there's enough desperate dumb money sloshing around in Zuckerberg's fear of missing out on the next big thing that they can get paid to pursue their pet projects without much concern for having to deliver short term impact on the bottom line.

I assume that at least some of the tension here is that facebook hired these guys to be the hotshot golden boys of sucking less at AI; so it isn't just an it's-only-money thing. I don't know whether or not this belief is accurate; but Zuck and friends certainly hunted down and paid for the various new AI hires as though they were capable of things that in-house or more readily available alternatives are not, so the battle over where their attention will be focused is presumably being waged on the assumption that having someone else do what they aren't doing isn't really a substitute.

What I would be curious to know is why the 'build god-machine' goal isn't being treated as the obvious winner just because you can have the god machine make facebook more addictive and better at serving ads. Do they think that the AI guys are drinking the kool-aide and the only thing they'll actually be able to deliver is incremental improvements; so they want those churned directly into products? Some degree of confidence that they will eventually manage it; but fear of missing out on some sort of short term advantage means that they don't care about what is achievable in 5-10 years? Genuinely zero interest in anything except making social media more of a hellscape; so they simply don't care?

If you're heading a company's AI division, ask yourself this:
Where does my paycheck come from? How did the company make revenue in previous quarters in order to pay me in this quarter?

The Family Of Apps (FoA) division of Meta, specifically digital advertising, are the actual superstars that keep the lights on there. And have made other projects like Reality Labs (RL) possible, supporting them until they could finally earn revenue as well.

I suspect that, while it would be socially controversial, planetary colonization would be a very strong case for IVF and some population planning.

For the amount of volume/mass required to ship a single human and support them in transit and on site you could ship a lot of embryos in cryo(it's careful plumbing; but a big dewar flask kept at cryogenic temperatures is downright lightweight compared to a full life support system); and shipping embryos gives you the option of bringing massive genetic diversity, thousands to tens of thousands of genetically screened parents worth of embryos in the space a single person would require.

Unless you've got some sort of advanced growth vats you would obviously need people onsite; but instead of dealing with the probably-impossible task of keeping a tiny breeding population's gene pool in order you'd just be defrosting and gestating specimens from a much larger pool of diverse embryos as needed. Presumably you'd initially go with an all-female colony, and only start defrosting males and trying to maintain a viable natural population once you had at least high single-digit thousands to low-mid tens of thousands.

I'm sure that such an arrangement would freak some people out; and you'd probably need to do some reasonably intense social engineering to keep everyone on-mission; but in terms of efficiency of genetic diversity there's a fairly compelling case to be made.

What sort of disaster do you have in mind that would render earth less habitable than mars?

Short of unstoppable replicator nanites turning the entire crust into grey goo; or very long term issues with the sun reaching EoL that will be an issue for basically anyone in the solar system, it's honestly hard to think of ways you could break it more badly.

Plenty of possibilities that will make people deeply miserable; or cause 80+ percent of the population to die horribly; but you'll still have a planet with the right gravity, an atmosphere and magnetosphere, some sort of ecosystem(even if it's just algal scum and cockroaches); some soil that isn't riddled with perchlorates, and so on.

about environmental causes loose their shit when you tell them to cut back or eliminate eating meat.

Geez I guess they people would want to line all those on the "carnivore diet" against the proverbial wall and shoot them, eh?

By the way....do these documents give one carbon credits if you go on a diet???

If so, what can you buy with these credits?

That's IMHO really overplaying it. I don't want to downplay food production effort difficulty, but saying "because we've never done it we can't" is like saying "Because we've never built a 5-meter-tall statue of a puffin made of glued-together Elvis dolls, we can't". We absolutely can, it's just a question of whether one thinks the investment is worth it. And I'm not talking out my arse, I have a degree in horticulture with a specialty in greenhouse cultivation. So much of the "keep the plants alive" systems we already do on Earth - you just need to get them there in an affordable manner.

The primary consumables are water and fertilizer. Nobody seriously is proposing building a colony that can't produce its own water. As for fertilizer, that would start off as an import, but a much smaller import than the food mass. On Earth, open-loop fert systems are fairly common, but they're slowly losing ground to closed-loop where you just maintain the EC, filter the returning solution, and every now and then due a nutrient-level test on the solution and individually adjust whatever nutrient might be lacking vs. the others.

We can consume lots of growing medium, like disposable rock wool cubes and the like, but we can also not do that. For example, it's perfectly fine to grow plants in clean sand / fine gravel - just clean it and sterilize it between uses. Something like pumice is better, though it slowly breaks down between uses. But you don't have to use anything special.

If you do LED lights, you may get a decade or so out of them. You can reduce shipping mass for replacement by going with designs that let you replace just the light boards from them (Mechatronix has lights like this for example), no need to resend e.g. the heavy heat sink, etc.

There's a million random things you use or that can wear out, from cleaning solutions to solution pumps to climate computers and and on and on. But they're not a meaningful import-mass, at least compared to food. Really, the big thing is fert. But regenerating fertilizer from waste (plant waste, human waste) should not be - industrially - immensely complicated. For the metals, burn to oxides / hydroxides, dissolve in acid, fractionally crystallize. You'll always lose some from the system, but we're not talking large amounts. For nitrates, Haber-Bosch is nothing exotic to adapt, and you have easy feedstocks (mining is complex, sucking in gases isn't).

(To elaborate about PELs: Venus's middle cloud layer is ~1-10mg/m3, depending on altitude, latitude, and what study you trust (our existing data isn't great). OSHA PELs are 1mg/m3 for an 8-hour shift. NIOSH's RELs are also 1mg/m3 for a 10-hour shift, with IDLH of 15mg/m3. Now, this has the two aforementioned caveats. On the downside, Venus's aerosols are higher molarity - 75-85% concentrated vs. ~20% on Earth. On the upside, the vast majority of the PEL/REL/IDLH risk is from inhalation, which obviously, you can't be doing in any atmosphere in our solar system other than Earth. Dermatitis thresholds are far higher. So again, so long as there's not rain/snow/dew/frosts, and you're at the right altitude/latitude combination**, you could probably spend some time outside in shirtsleeves and a facemask, and feel an alien breeze against your skin.

** One also has to stress latitude, not just altitude, as it's cooler for a given altitude as you get closer to the poles. While Venus's middle cloud layer climate is "similar" to Earth's, it's a bit on the warmer side for a given pressure than Earth's - and because an aerostat rides "down" in the atmosphere vs. its internal pressure, esp. at night when it's no longer being heated by the sun, it amplifies the impact. So if you're going to be living in the envelope, you need to find the right balance between how far you want to go below 1atm and how hot you want to have it be outside. Shifting more poleward helps find a better balance between the two (at the cost of lower sunlight availability for solar power vs. the super-bright equatorial regions). It also shortens your effective day (faster superrotation period). You probably don't want to go fully to the poles, though, because of the polar vortices (though how turbulent they are is still an open question).
