<p>Let me share a hot take. I am deliberately taking this somewhat to the extreme, so please attack the idea not the person. Looking for thoughtful replies and good counterpoints, rather than language zeal.<p>Let's assume that you need to write a program with a given set of requirements, and that you have a magic wand that can instantiate a high quality implementation of the program in any programming language instantaneously and for free. My hot take is that you would not want to choose Go, and you would likely want to choose Rust.<p>The Go implementation will have higher memory and CPU consumption due to garbage collection, while still being subject to memory bugs. The Rust implementation would be as efficient as possible on the given hardware with minimum memory/CPU, and it would be immune to memory bugs.<p>In my view, the biggest challenge with Rust, and where Go wins, is the relative difficulty of writing in Rust as the language is significantly more complex. With LLMs this is becoming a non-issue, and we are getting ever closer to having this magic wand (I'd argue that for smaller programs the wand already exists today). The article advocates that Go has excellent readability. I agree that Go has trivial syntax, but given that it's so verbose, I actually find it easier to read Rust code. Its higher expressivity allows you to see the higher level intention of a piece of code more easily.<p>Many of the other benefits the article mentions for Go are equally applicable to Rust: compiler error messages are super detailed and a great help to coding agents, auto-formatting, a great language server, and a package ecosystem.</p>

<p>> But it’s tough to engineer much these days. Instead I find I’m PM’ing the bots more than solving problems.<p>I’m genuinely curious about your perspective as I have almost the diametrically opposite view. I love chatting with the bots as they can build the thing I want, <i>how</i> I want it, much faster than I could. The output still feels mine. Maybe not line by line, but definitely architecturally. The speed makes me feel, sometimes, almost superhuman.<p>Do you take emotional ownership in the shape output artifact itself, or merely that it works?</p>

<p>> So we're going to skip becoming carbon neutral and go straight to carbon negative<p>Yes, when the effects on the environments are so bad that there can be no denying anymore because they affect everyday life of almost all people.<p>I am not saying this is a good option. I am saying that I don't see an alternative to get a world wide mobilization. Do you see China and the US becoming carbon neutral in the next 10 year?<p>The annoying "magic" dig was unnecessary. With (clean) energy abundance you can indeed capture enough CO2 to make a world wide impact.</p>

<p>Sadly I think the only solution is to invest to build more energy infrastructure and more AI, so that in the future when the shit really hits the fan we have enough energy and assistance from AI to create a scalable technology to pull CO2 out of the atmosphere proactively.<p>In my view there is no credible future in which the world will become carbon neutral in 1 or even 10 years. It just ain't happening. This is one of those problems where the train is already running down the hill, and we need to engineer a way to catch it. We cannot stop it anymore.</p>

<p>The word ‘crank’ is a dismissive insult. Wolfram is definitely eccentric, probably hard to work with, but also undoubtedly smart. What good does it do to dismiss him? He’s doing nothing wrong spending his own money the way he wants to. And who knows something will come out of this. Similar to GP I’d like to see more of this.</p>

<p>You are creating 20 other engineering problems but not 20 other physics problems. You cannot put those in the same bucket.<p>It remains to be seen how efficiently those engineering problems can be solved, but none of the commentators here have any real insight about that (myself included). My money is on the ingenuity of the engineers that are working these problems.</p>

<p>The plan is to launch a constellation of smaller AI sats not a monolithic large data center. The calculations I have seen actually have a smaller radiator area than solar panels. Scott Manley’s has a video on this where he goes into some numbers.</p>

<p>I don’t think people are confused between the two. What’s happening is that drive by objections have no real way to assess viability. That calculation you ask for has line items in it that greatly depend on engineering optimizations that, unless you work in the field, are hard to estimate accurately.</p>

<p>The always on orbit exists and is called a dawn-dusk Sun synchronous orbit. It is an orbit that is always above the terminator (line between night and day) where it can face the Sun 100% of the time.<p>This orbit has to rotate about a degree every day to follow the terminator as the earth orbits the Sun. It uses the equatorial bulge of the earth to achieve that rotation without have to spend rocket fuel. It is really quite interesting.</p>
