<p>"The Wire" TV show portrays these things well. In it, the powerful people often have the least clue about anything. They are just playing the game and often winning by sheer luck. They also often do fuck up, but because they are powerful, are able to get other people to take the hit for them or build a narrative that hides the fuck up.<p>The older I get, the more I think that this TV show is actually the most realistic portrayal of how the real world works there is.</p>

<p>There can also be an argument that laws are always only an approximation, and they should be broken in corner cases where they clearly don't work as intended.<p>Civil disobedience can also be a useful societal force, and with perfect law enforcement it becomes impossible.</p>

<p>We've had the AI tools for maybe two years, and they have only gotten really good in the past half a year or so. For fuck's sake, adopting electricity took like 50 years, why would you expect to see any kind of effect from the AI so quickly? The tools are still developing - rapidly - and people are still figuring out the best usage patterns for it.</p>

<p>I used to be a university researcher in theoretical physics and, in that field, everyone uses it, but I suppose that would count as "very specific math research" Any kind of complex integrals, systems of equations, etc. and Mathematica is invaluable, and, as I said, so much ahead of Sympy.<p>You could do stuff other than theoretical physics research with Mathematica, though. I has a lot of functionality and I always felt that I used only a tiny fraction of it.</p>

<p>I've had the same idea. Especially regarding anxiety. You start getting anxious and scared of everything, because your brain knows that your body is out of shape and incapable of dealing with stuff if anything happens. If you can't deal with any problems, then you must constantly be on lookout for them so that you can avoid them.</p>

<p>Every major technological invention nowadays quickly breeds open source clones that evolve to be on par with the commercial ones on some time scale. Why hasn't this happened to Wolfram Alpha/Mathematica? I know there's Sympy, but it's so far behind Mathematica that it's not even comparable. Is the heavily mathematical nature of the tool somehow an insurmountable obstacle to the open source community?</p>

<p>To be fair, multiplayer via LAN is such a marginal feature nowadays that you can't really blame the companies for not supporting it. You don't really need "greedy corporate fucks" explanation for this; it's just that you don't want to develop, support and test features that maybe 0.1% of the user base is going to use.</p>

Before Trump started threatening everyone, we had no problem using US tech.</p>

<p>Yeah. We are only just beginning to get the most out of the internet, and the WWW was invented almost 40 years ago - other parts of it even earlier. Adoption takes time, not to speak of the fact that the technology itself is still developing quickly and might see more and more use cases when it gets better.</p>

<p>Indeed. Most large companies don't need AI to increase productivity - they just need to stop wasting time on stupid bullshit. However, figuring out what is stupid bullshit and what is not seems to be an impossible task, and I don't think AI is going to help here at all.</p>

<p>> I think companies will need fewer engineers but there will be more companies.<p>This would be strange, because all other technology development in history has taken things the exact opposite direction; larger companies that can do things on scale and outcompete smaller ones.</p>

<p>My experience has been that AI is much more useful on my own systems than on company systems. For AI to (currently) be useful, I need to choose my own tooling and LLM models to support AI centered workflow. At work, I have to use whatever (usually Microsoft) tools my company has chosen to purchase and approve for my corporate computer, and usually nothing works as well as on my own machine where I get to set it up as I want.</p>

<p>Western individualistic thinking struggles with the concept of biological limits. Our genes influence nearly everything we do or are, and there's nothing we can do about it.<p>Years ago, I read the book "The Sports Gene" by David Epstein. I was particularly struck by how sled racing dogs are now bred for <i>motivation</i> to train, rather than just their physical running ability. That is, breeders select for genes that make it so fun for the dogs to run that they keep going, while the dogs not bred this way just give up when they feel a little tired.<p>The story made me really think to what extent is my motivation to exercise, or do anything for that matter, affected by my genes? And if this sort of stuff is genetic, is there any more point to punishing myself for laziness than to feeling bad for being too short?</p>

<p>I don't know if data centers in space make sense or not, but I'm really not liking these comments that say something is "too expensive" or "too hard" without actually crunching the numbers to verify if it actually is. It's like you point out a number of completely obvious problems with the scheme and immediately, without any detailed analysis or expertise (I know this, because surely you can't have expertise in all of the problems you cited) in the said problems, claim that they are completely impossible for anyone to ever solve.<p>> 1. every gram you need to send to space is costly, a issue you don't have at ground level<p>This is a one time cost. Maybe the running costs are cheap enough to offset this.<p>> 2. cooling is a catastrophe, sure space is cold, but also a vacuum, so the cooling rate is roughly the infrared radiation rate. This means if you are not careful with the surface of a satellite it can end up being very slowly cooked by sunlight alone not including running any higher heat producing component (as it absorbs more heat from sunlight then it emits, there is a reason satellites are mostly white, silver or reflective gold in color). Sure better surface materials fix that, but not to a point where you would want to run any heavy compute on it.<p>I would assume the people designing this are "very careful" with everything they put in the data center. If achieving the cooling is only very hard and requires careful material engineering, then it can be worked out and they will get it done. If it is impossible, then this will not happen, but I'm a physicist myself and I can't tell without a very involved analysis whether it is impossible or not to get enough cooling power for this in space, considering all, possibly ingenious ways to engineer the surfaces of the data center to dissipate a maximum amount of heat.<p>> 3. zero repair-ability, most long running satellites have a lot of redundancy. Also at least if you are bulk buying Nvidea GPGPUs on single digit Million Euro basis it's not rare that 30% have some level of defect. Not necessary "fully broken" but "performs less good then it should/compared to other units" kind of broken.<p>I suppose they could make something like the International Space Station, which would get regular traffic back-and-forth exchanging and servicing hardware as needed.<p>> 4. radiation/solar wind protections are a huge problem. Heck even if you run things on earth it's a problem as long as your operations scale is large enough. In space things are magnitudes worse.<p>Again, it's not a question whether this is "problematic"; everything about putting data centers in space is. The question is whether, with huge amount of work and resources, they can engineer a solution to overcome this. If they can, it's again a one time cost for the data center that might be offset by the running costs of the facility.<p>> 5. every rocket lunch causes atmospheric damage, so does every satellite evaporating on re-entry. That wasn't that relevant in the past, but might become a problem just for keeping stuff like Starlink running. We don't need to make it worse by putting datacenters into space.<p>> 6. Kessler Syndrom is real and could seriously hurt humanity as a whole, no reason to make it much more likely by putting things into space which don't need to go there.<p>These are collective problems for the whole of humanity and will not concern an individual actor such as Elon Musk who wants to send more satellites into space.</p>
