  • That’s why they made it a pin.

    Sure you can sell an app on the App Store, but most people won’t pay more than 5 bucks for an app, and even that’s stretching it. And the subscription market is already over saturated. So how do you make a boatload of cash? Sell overpriced hardware that needs to be “upgraded” every year or 2 to use new features, and include a subscription to use the thing in the first place.

    They wanted to pull an Apple and lock people into their hardware ecosystem. I guarantee there was a plan for them to release an AI phone in the next 5 years if this thing did well.

    What they missed is Apple products are generally pleasant to use on a daily basis. From what everyone said, this thing was hot garbage and slow to respond to queries.


  • If it really did, then nasa would not have committed to this hare brained scheme of musk’s.

    The fact that the SpaceX proposal was accepted by an interim director who then went to work at SpaceX 6 months later, and no one has investigated this or challenged the acceptance of this contract tells me that safety is clearly not the priority. If safety was the priority, the new director would have looked at the current proposal and demanded a renegotiation or reconsideration.


  • If only that philosophy existed today.

    NASA landed on the moon with 1960’s technology, not because it was easy in the 60’s, but because every single aspect of the mission was planned, tested, rehearsed, and made as simple as possible where it couldn’t have a redundancy. The only time something went really wrong was when a faulty tank exploded on Apollo 13, but due to having an entirely separate craft in the form of the lander attached, the astronauts were able to ride out the failure all the way around the moon and back to earth. Oh yeah, even the orbit they picked would let the whole spacecraft fly around the moon and come back to earth without having to do any engine burns.

    Look at planned missions today. Launch the Human Landing system. Have it sit in space for an unknown amount of time while anywhere from 6 to 12 refueling rockets are launched to refuel the lander. Relight lander engines in earth orbit, go to moon, relight engines again to orbit the moon. Launch the Orion spacecraft with crew on board, this also must burns its engines once at the moon to enter lunar orbit. Rendezvous and dock with the HLS, transfer crew and supplies over. Undock Orion, relight HLS engines for a 4th time to deorbit and land HLS. Use an elevator to get from HLS to the lunar surface for the next week or so. Board the HLS, which needed at least 6 refueling tankers full of cryogenic fuel to get to the moon and has now been sitting on the 200 degree lunar surface for a week, and light the engines a 5th time to take off and enter lunar orbit. Rendezvous with Orion, and return home. NASA has demonstrated that Orion can do the mission. But HLS has not even shown the technical capability of doing this. Its engines have never been relit in space, it has never sat in space for a week to see what happens to the engines. The entire interior isn’t even built yet and NASA is just using a 9 meter steel circle to train astronauts on the airlock section because no one knows what it will look like.

    This mission couldn’t be more complicated if you tried. Apollo needed a total of 1 engine relight on the transfer stage, and 2 engine relights on the command module: one to enter lunar orbit, and one to leave and return to earth. The lander used pressure fed engines that only needed to work once each. One engine got them from orbit to the surface, one got them from the surface to orbit. If the Ascent engine didn’t work, NASA had plans for everything from literally jump starting it with the descent module’s batteries like it’s a dead car, to having an astronaut use bolt cutters to cut the safety pins on the engine so the valves can be manually opened.

    If your car doesn’t start in the morning, you might call off work and get it towed to a mechanic. What do you do when you’re trying to leave the moon, and your rocket engines won’t light because they’ve been sitting in space for almost 2 weeks? The nearest rocket engineer is 240,000 miles away back on earth, and so are all the spare parts. And what do you do if only some of those engines light, and the others either don’t or explode while you’re on a suborbital trajectory. Complexity kills on harsh environments. Space is one of the harshest environment we’ve ever been in, so things need to be as simple as possible and known to work.




  • Space travel is very expensive and NASA has a very small budget these days.

    Back during the space race, NASA could afford to launch multiple missions per year. Now they can barely afford to maintain existing missions and are lucky to launch a major missions every few years. Which is why they’ve moved to buying space on commercial missions, as it’s cheaper to only pay for a spot on a rocket/craft than to pay for the whole thing.

    NASA also has to justify its missions to congress. Sending rovers to mars and probes to the moons of Jupiter and Saturn have actual scientific interest and can answer questions about the formation of the solar system, and the viability of life off of earth.

    Slingshotting something really fast sounds cool as fuck, but there’s not much data to be gathered there. We’ve also recently beaten the “fastest man made object” record with the Parker Solar Probe, as it’s currently whipping around the sun at ludicrous speeds while it collects data about the solar atmosphere and magnetic fields. It’s moving a lot faster than voyager ever did, as it needs an insane amount of speed to orbit so low to the sun. It’s actually much cheaper, fuel wise, to travel to Pluto than the sun.

    So why waste billions of dollars to fling something out into deep space? We have barely even seen all Of the celestial bodies in our own star system, and there’s not much to be learned about the empty vacuum beyond the sun. The only justifiable reason would be to send a probe to another star system entirely. But that probe alone would have to be the largest, most expensive space craft humanity has ever built. It would need to be able to power itself for centuries, have a communication system capable of sending data over interstellar distances, and likely need a way to autonomously harvest its own fuel, as there’s very little point in sending a probe screaming past Proxima Centauri and taking a few hazy pictures of planets as it goes. We’d want the probe to be able to stay in and explore the new star system, and the only way to do that is to have enough fuel to move around an entire system, or create more fuel as it goes. Something like that has never even been tried before, and the risk is high when you won’t know if it worked or not for a few hundred years.

    Who controls the streetlight blockchain in your idea? You think the government is going to responsibly manage a system that is large enough to be impractical to alter? My local government is barely responsibly enough to manage basic utility maintenance, we’ve had 3 water main bursts in a month and it hasn’t even been below freezing that whole time.

    I can’t believe a human being living in the world doesn’t see that any implementation of a secure blockchain requires massive funding for infrastructure. That money comes from 1 of 2 places, illegal enterprises that maintain control for security and manipulation, and legal corporations that will maintain control for financial security and manipulation. Modern governments don’t run projects like this anymore, they contract them out to corporations.

    Keep in mind that the only practical use of blockchain that anyone has found so far, has been as a currency that requires no ID. The most famous use of these currencies was by John Mccaffee, who used crypto currencies to help him evade authorities for nearly a decade. So I don’t have much faith in a technology that has only shown a benefit to criminals with so much money that cash becomes impractical. Nor do I have to remind you that wealthy private individuals have been able to manipulate crypto markets with hilarious ease, like how Musk pumped and dumped Doge Coin years ago with a single tweet and most likely made millions in private, untraceable money.

    Just because something sounds cool on paper, and makes it seem like it skirts governments and corporations, doesn’t mean it works in practice. Large entities inherently have more resources, and are primed to steal new technologies for their own use, especially when implementing that technology requires huge funding for infrastructure.




  • Kinda like how Elon promised a mars colony by 3 years ago, and his big rocket exploded on its first flight a few months ago.

    Or how full self driving has been ready “next year” for the passed 5 years.

    Hyperloop was going to revolutionize transportation, by having a train in a vacuum tunnel, and is currently an abandoned tube in the desert.

    The boring company was going to create high speed car tunnels under cities, and it’s test track is a 30mph traffic jam, but now underground.

    Solar city was going to put solar tiles in place of your shingles and offset your power usage, but the demo musk showed was an actual fraud, and there were no solar panels.

    Last but not least, spaceX promised “rapidly reusable rockets” with a 10x decrease in cost to low earth orbit. The fastest turn around they’ve ever had was a month or so, about as long as the space shuttles’ fastest turn around. The falcon 9 still costs between 50 to 60 million per launch, even if it’s a reused booster or not, and the space shuttle was capable of taking crew and cargo/payload at the same time, while the falcon can only take one or the other.

    Musk companies have a long history of promising the moon and delivering playground sand. Don’t buy any of his products and don’t fall for his “saving humanity” bullshit. He’s just a conman who’s defrauding investors for billions.

    This is the part they’re missing: apple actually care about the appearance of quality.

    I’m not saying apple makes quality products, there’s some good debate there that they really don’t. But they certainly foster the belief that apple products are superior in quality to their competitors.

    Unity is a great engine when it’s used well, but it doesn’t have a reputation for quality. It has a Reputation that says “anyone can publish a bolted together asset flip and make a quick buck off of twitter hype”

    I doubt apple would acquire unity based purely on the fact that unity does not adhere to apple’s ideals on branding. Apple tends to buy rights from young companies that don’t have large established brands yet, because it’s easier to fold them into the cult of apple. An established brand with a known reputation would be a tough sell, especially when Apple has the resources to simply make their own product that’s tailored to their hardware.
