Payment processing is one of the most tightly regulated, and some might say corrupt, industries. Replicating the tech wouldn't be difficult. The social and regulatory part is effectively impossible for anyone who's not already in the inner circle.
Ironically Square isn’t good at anything in particular. Square fails to have a good point of sale (Toast wins) and fails for online store fronts (Shopify wins). Square is in a position where they spread themselves thin and aren’t at the top of anything in particular.
With light CRM, Staffing, and Banking tools, it seems like Square's strategy is to be best-of-suite for small businesses rather than best-of-breed.
I've never seen Toast outside of bars/restaurants (although they are ubiquitous in that segment). Every other service or retail shop has been Square, especially farmers markets and craft fairs.
i think they dont have a great moat in their individual offerings, but across square, cash app, and afterpay they offer a pretty good suite of products for the entire transaction stack.
It obviously never became completely irrelevant. But I think programmers spend a lot less time thinking about memory than they used to. People used to do a lot of gymnastics and crazy optimizations to fit stuff into memory. I do quite a bit of embedded programming and most of the time it seems easier for me to simply upgrade the MCU and spend 10cents more (or whatever) than to make any crazy optimimzations. But of course there are still cases where it makes sense.
While thinking less about memory optimizations is possible since we have more memory, it was enabled by the languages and libraries we use. Fourty years ago, you were probably implementing your own data structures. Sure, there were plenty of languages that offered them back then (LISP was based on linked lists, and that language is from the 1960's). Chances are you weren't using such languages unless you were using big computers or writing software that didn't handle much data. These days, pretty much any language will provide at least some data structures and their related algorithms. Even systems programming languages like C++ and Rust. Of course, there are an absurd number of libraries if you need anything more specialized.
We live (or at least used live) in a very nice climate equilibrium with the CO2 level we had. Pushing us into another climate equilibrium looks very dangerous for human civilization. However I concede that it might be advantageous for certain plants, but I am not a plant so I am mostly concerned about human civilization.
> However I concede that it might be advantageous for certain plants
Plants are highly dependent on their climactic settings, upending a climate equilibrium is awful to the average plant. And looking at past climactic change events, "another climate equilibrium" is something that happens on kiloyear scales (ages, in geochronologic units).
This is the main point I think. I am very much convinced that SpaceX is capbable to put a datacenter into space. I am not convinced they can do it cheaper than building a datacenter on earth.
I would be a lot more convinced they had found a way to solve the unit economics if it was being used to secure billion dollar deposits from other companies rather than as the narrative for rolling a couple of Elon's loss making companies into SpaceX and IPOing...
Beaming energy always sucks. Without some very fundamental discoveries in physics nobody will every make this work economically. This isn't just an engineering problem, it's a physics problem.

> Bezos has been pushing manufacturing-in-space for a long time, as a ideal candidate for what to do in space that you might prefer to not do on Earth. Robotics, AI automation, manufacturing - combo it in space, let the robots manufacture for us in space.
LOL, this seems so far off from the reality of what manufacturing looks like in reality.
- sending raw materials up there
- service technicians are necessary ALL THE TIME, in fully automated production lines
- sending stuff back down
Maybe I lack vision, but data centers in space is a 1000x times better idea and that is already a terrible idea.
Space manufacturing is a real thing, there are already companies trialling it. The factory is small, satellite sized, and it deorbits when the manufacturing run is done. The results are protected enough for them to be picked up from Earth.
The justification (today) is that you can do very exotic things in zero-G that aren't possible on Earth. Growing ultra-pure crystals and fibre optics and similar.
Ok, that I might buy. If there is a product one can build in zero-G that one cannot build on earth. Especially something like growing crystalls. Sure. But trying to compete with something that can just as well be build on earth on the premise that it will be cheaper to do the same thing just in space is insane.
It's the same issue that I have with data centers in space. I don't think there is any big technical hurdle to send a GPU rack into space and run it there. The problem is that I have a hard time to believe it is cheaper to run a datacenter in space. When you have to compete solely on cost, it will super hard.
I don't think it's insane. It might not work or be competitive but it's not obviously insane.
In a frictionless economy governed by spherical cows it'd be insane. But back here on Earth, AI is heavily bottlenecked by the refusal or inability of the supply chain to scale up. They think AI firms are in a bubble and will collapse, so don't want to be bag holders. A very sane concern indeed. But it does mean that inferencing (the bit that makes money) is constantly saturated even with the industry straining every sinew to build out capacity.
One bottleneck is TSMC. Not much that can be done about that. The other is the grid. Grid equipment manufacturers and CCGT makers like Siemens aren't spinning up extra manufacturing capacity, again because they fear being bag holders when Altman runs out of cash. Then you have massive interconnection backlogs, environmentalists attacking you and other practical problems.
Is it easier to get access to stable electricity supplies in space? It's not inconceivable. At the very least, in space Elon controls the full stack with nearly no regulations getting in the way after launch - it's a pure engineering problem of the sort SpaceX are good at. If he needs more power he can just build it, he doesn't have to try and convince some local government utility to scale up or give him air permits to run generators. In space, nobody can hear you(r GPUs) scream.

Wouldn't he be able to float solar panels and GPUs out into international waters and run them on cargo ships powered by bunker fuel much (much much) cheaper than launching them into space?
Building nuclear-powered and solar powered datacenters in places with low population density will still be cheaper. Do you think Mongolian government won't allow China to build datacenters if the price is right?
It might be easier in China but that doesn't help Elon or Americans.
Solar powered datacenters on Earth don't make sense to me. The GPUs are so expensive you want to run them 24/7 and power cycling them stresses the components a lot so increases failure rate. Once it boots up you need to keep the datacenter powered, you can't shut it down at night. Maybe for CPU datacenters solar power can make sense sometimes, but not for AI at the moment.
Nuclear is super hard and expensive to build. It probably really is easier to put servers in space than build nuclear.
It’s not necessarily cheaper energetically to get stuff from an asteroid than from Earth. You’d have to accelerate stuff from a wildly different orbit, and then steer it and slow it down. Metric tonnes of stuff. It’s not physically impossible, but it is wildly expensive (in pure energy terms, not even talking about money) and completely impractical with current technology. We just don’t have engines capable of doing this outside the atmosphere.
> It’s not necessarily cheaper energetically to get stuff from an asteroid than from Earth. You’d have to accelerate stuff from a wildly different orbit, and then steer it and slow it down.
Delta V from just about anywhere in the solar system is lower than launching from the surface of Earth. You could launch stuff from Mars and bring it back to Earth orbit with less energy than launching it from Earth. The rocket equation is really punishing.
Right. The alternative is not to send materials from Earth for processing in space, that would be stupid. We send finished stuff, which were manufactured on the ground. But you don’t mine finished widgets from asteroids. You mine ore that needs refining and processing before being used to manufacture things. This ore is orders of magnitude heavier than the finished products, never mind all that’s required to do anything useful with it.
I think you might have no sense of what it takes to go from a raw mined material to something that can be used in a factory. I am not saying it cannot be done. I am just saying it cannot be done in a way that is cheaper than on earth.
The show For All Mankind kind-of hinted at how the labor problem would be solved: recruit like the military and promise huge bonuses that will probably not be realized because space is risky business
I think it makes more sense if you invert the manufacturing cycle.
Automated asteroid mining, and asteroid harvesting, are potential areas where we have strong tech, a reasonable pure automation story, and huge financial upsides. Trillion dollar asteroids... If we’re sourcing metals out there, and producing for orbital operations or interplanetary shenanigans, the need for computing and automation up there emerges.
And I imagine for the billionaire investor class now is the window to make those kinds of plays. A whole set of galactic robber barons is gonna be crowned, and orbital automation is critical to deciding who that is.
Ideally one also manufactures them. But when you buy solar panels, one get's 30+ years of lifetime out of it. So once installed. It's tricky for China (or whoever makes time) to use them as leverage. If you cut off oil or gas there is only a few months of reserves.
Huh? What prevents you from installing them "all at once"?
The downside is obviously a long stretch of no sun, and for Europe winter being both low solar production and high energy demand due to heating which the soon-to-be-cheap grid scale batteries don’t really fix. The logistics of PV don’t seem difficult though - it seems by far the easiest of the power generation methods, even if the synchronization can get a bit tricky in a large grid.
Because manufacturing isn't there to do everything at once. You install say 50gw per year, each year. In 30y you need to replace first 50gw batch and so on
Solar panel materials are extremely toxic (current tech), or are toxic unless properly processed (hopefully, but likely, future tech).
So they won't be made in the EU, since nobody wants to make concessions here. Solar panels have the same problem as oil and mining: they will destroy nature somewhere, otherwise it doesn't work.
Crystalline silicon solar panels have about 95% market share, and "By weight, the typical crystalline silicon solar panel is made of about 76% glass, 10% plastic polymer, 8% aluminum, 5% silicon, 1% copper, and less than 0.1% silver and other metals."
Everything that is manufactured is made out of atoms, and you can say that any manufacturing requires some nature destruction in the aggregate. But solar electricity requires far less mining and natural despoilation than fossil-fueled electricity.
Solar panels contain quite a bit of lead, and small amounts of cadmium. Lead can be taken out if you're willing to pay a bit more, in other words it never is. Cadmium is required. Other metals are sometimes present.
So solar panels are classified as hazardous waste.
Cadmium is only required in cadmium telluride solar panels, which have less than 5% global market share. Lead solder is still common in crystalline silicon panels, though not universal; modules built with heterojunction cells typically avoid solder because the cells can't tolerate temperatures that high:
Humans also make silly mistakes.
