SpaceX and xAI Are Merging Into a Very Silly-Sounding Conglomerate. Take It Seriously

SpaceX and xAI Are Merging Into a Very Silly-Sounding Conglomerate. Take It Seriously

SpaceX is acquiring xAI. Ever since this merger of two Musk companies became a rumor, crazy numbers like $1.5 trillion started being thrown around when discussing the total valuation of SpaceX, so you might sum it up by saying “Combining SpaceX and xAI gets you the biggest IPO of all time!” and yeah, that’s more plausible now than ever. For reference, SpaceX’s valuation was estimated at around $800 billion less than two months ago. 

But is this merger as silly as it sounds?

The combined company will be a “vertically-integrated innovation engine,” according to a new SpaceX press release with Elon Musk’s personal signature on it. By his own reckoning, the company now deals in “AI, rockets, space-based internet, direct-to-mobile device communications and the world’s foremost real-time information and free speech platform.” Another way of saying this might be that SpaceX is now the company behind vertically-landing rocket boosters, the majority of the satellites currently in orbit, very fat rockets that tend to explode, an ISP, the microblogging app known as X, a sassy chatbot called Grok that’s famous for lewd images, and much much more.

SpaceX will now own, for instance, Grokipedia, the AI-written, anti-woke parody of Wikipedia. And remember Vine, the defunct 6-second video social media app? Yes SpaceX, which possesses billions of dollars in Pentagon contracts and is responsible for crewed NASA missions, now owns the rights to Vine too. Musk claims he’s bringing it back “in AI form.”

As many have pointed out before me, SpaceX became a genuinely indispensable player in humanity’s aerospace and space travel efforts through an iterative process involving an extraordinary number of spectacular and public rocket explosions that almost certainly would not have been tolerated if SpaceX were a government agency. It has always walked a delicate tightrope, keeping boring people happy, while also subject to the silly stuff and horrors that go along with being run by Elon Musk.

Gwynne Shotwell, the president and COO of SpaceX, has been described by the Wall Street Journal as “a Musk translator, especially for officials who depend on SpaceX but are occasionally unnerved by his activities.” In that same Journal article, former NASA administrator Bill Nelson—also a Democratic ex-Senator—called Shotwell, “the steady hand” at the company, and added, “I have a great deal of confidence in her. Because of that, I have a great deal of confidence in SpaceX.”

Back in 2022, when Musk was in the middle of buying Twitter in as chaotic a fashion as possible, Nelson says he called Shotwell, and said, “Tell me that the distraction that Elon might have on Twitter is not going to affect SpaceX.”

“I assure you, it is not,” he says she told him. “You have nothing to worry about.” 

Now imagine being Shotwell four years later. Twitter is now X. Last year, the proprietary AI chatbot on X briefly started calling itself “MechaHitler” at one point, and then it generated tons of scantily-clad pictures of children. So not only has the drama increased, but you’re the president and COO of the company that made all that stuff too.

And imagine Shotwell having to handle this merger while Musk, the attention-starved celebrity CEO of this conglomerate has spent the last few days trying to post his way out of any consequences or disapprobation brought about by the public disclosure of emails in which he repeatedly asked Jeffrey Epstein if he could party on his private island.

So one can only speculate what Musk’s mental state was when he finalized the plans for this merger. But what stands out to me is that he wants investors in xAI and SpaceX—and perhaps starting in June, future holders of publicly traded SpaceX stock—to believe that this merger creates a company that gels and has a unified agenda. But you might want to take as big of a bong rip as you can before you try and get your head around that agenda as Musk describes it in his press release:

This rocket and AI company will actually be an AI-in-space company, you see, because, according to Musk’s estimate, “within 2 to 3 years, the lowest cost way to generate AI compute will be in space.” After all, “in the long term, space-based AI is obviously the only way to scale.” Obviously.

But training models with space compute is just the beginning, because Musk claims that by combining these two concepts, they’ll be “scaling to make a sentient sun to understand the Universe.”

Companies don’t have to always make sense. Samsung has hotels. Red Bull has a nature magazine. Konami has aerobics gyms. Sometimes these incongruities are prosperous leftovers from a different era for a company, but sometimes they reveal the caprice or frivolity of company leadership, which can be no big deal.

But then again, it’s not farfetched to think that Elon Musk’s caprice—and the fact that an economically powerful subset of Wall Street bulls think that caprice is tantamount to wisdom—may soon control the world’s best-funded AI company at a time when AI is the load bearing structure propping up the whole economy. If the IPO goes well (the New York Times’ sources say Musk hopes it will raise $50 billion), that AI company is going to be in your 401(k) while it’s also in charge of the lives of astronauts. 

In other words, we’re headed for a time when the Wall Street bulls will have to be right. More than ever Elon Musk’s caprice may have to actually be wisdom, as implausible as that may be. AI had better not be a bubble if this IPO goes well, and the value of Musk himself had better not be inflated either. All of our well-being may just depend on it.

If you were thinking of seeing Minions & Monstersor at least taking your kid to see it, here’s something to sweeten the pot: George Lucas is in it.

Illumination head Chris Meledandri broke the news in a recent Collider interview, where he revealed the Star Wars creator is secretly a fan of Despicable Me’s chatty champions. “It was such a thrill to learn and share that with the team,” said Meledandri, “He’s among a very small group of people who the entire studio shares a level of respect for that is just off the charts.” Given Lucas’ affection for funny little guys, it makes sense that he loves the biggest little guys of our current movie era.

Now that they knew they had Lucas in their corner, the team decided what the hey, get him to do a voice for the movie. Meledandri said an “idea for a character” was born that fit the bill, and they got “a fast yes” when it was pitched. At time of writing, Illumination’s quiet on who Lucas will be, but it’s worth noting that Minions & Monsters takes place in the 1920s as the crew try to make their own movie. Lucas’ love for older films is apparent in Star Wars and Indiana Jones, so maybe he’ll be a director that ends up getting trampled by the Minions. Maybe he’ll even be one himself who just looks like a little yellow George Lucas, that’d be fun.

Look for Minions & Monsters to hit theaters on July 1.

With electricity costs soaring, home batteries have never looked so attractive. Whether you want to store the excess generated by your solar panels or simply buy electricity at the cheapest possible rate to use later when power is most expensive, a home battery can help. It’s never been easier to get a home battery installed, but this rapidly expanding market can be confusing, and there are several things to consider before you buy.

I’ve spent months researching home batteries, chatting to folks who use them, and then having one installed myself, and I have tips for anyone interested in getting a home battery of their own.

Why Would You Want a Home Battery?

There are several reasons you might want to invest in a home battery, and they are not mutually exclusive:

  • You want to store excess power from your solar panels.
  • You want to live off-grid.
  • You want to guard against power outages.
  • You want to buy electricity at a cheap rate and store it for use later.

Home batteries are a win-win, potentially benefiting power companies too, because battery storage is an essential part of grid balancing and can help manage and make the most of the intermittent power generated by renewables (solar, wind, waves).

How Do Home Batteries Work?

A home battery is like a big power bank for your home. But rather than lithium-ion, they tend to be lithium iron phosphate (LFP or LiFePO4), because it is safer, more durable, and less prone to thermal runaway. In other words, less likely to overheat and burst into flames. There are a few manufacturers working with sodium-ion (Na-ion) batteries, which are potentially cheaper, more environmentally friendly (they don’t require lithium), and perform better in the cold, but they are also larger and don’t last as long.

Home battery technology is often the same as you’ll find in electric vehicles. Some folks have even suggested employing EV batteries as home batteries. But there are potential issues with that, not least finding your car battery drained in the morning. EVs are also driving the technology forward toward solid-state batteries, which are smaller for the same capacity, safer as they don’t have liquid electrolytes inside, and longer lasting.

Many home batteries come in modular systems, so you can add the capacity you want, but they require an inverter to convert the DC (direct current) power stored to AC (alternating current) power you can use. Folks with solar panels, or those who plan to add them in the future, should opt for a hybrid inverter, which can also convert the power from the panels for use or storage.

Inverters have different power ratings in kilowatts (kW) that dictate how much power you can draw at any given moment. Households with modest needs may get by with a 3.6-kW inverter, but that limits your continuous draw to 3.6 kW. They usually have a peak load capability that goes higher, enabling you to pull more for a brief period. If you have high-demand appliances like an EV charger or heat pump, you will want at least 5 kW, and folks with larger demands or larger batteries will want to go higher (6 to 10 kW).

What Should I Look For?

There are several things to watch out for when buying a home battery:

  • Capacity: Measured in kilowatt-hours (kWh), this tells you how much total energy the battery can hold.
  • Power output: Measured in kilowatts (kW), this shows how much energy the battery and inverter can deliver at any moment.
  • Depth of discharge: This is how much of the battery’s capacity you can safely use without damaging it.
  • Efficiency: This is the percentage of the power you put into the battery that you can actually use, because some energy is always lost in the storage process.
  • Warranty: This is a guarantee about the minimum performance you can expect before a battery degrades (they all degrade over time), and it’s often stated in years and charging cycles (whichever comes first). For example, EcoFlow promises at least 70 percent capacity after 15 years or 6,000 charging cycles.

How Much Home Battery Do You Need?

It can be tricky to calculate how much battery capacity you need, and it depends on your use case. If you want to guard against outages or live off-grid, you must consider how much power you use over time and also the sum of your maximum power usage at any given moment to ensure your capacity in kWh and output in kW are enough. If the output is not high enough you may not be able to run power-hungry appliances at the same time, so you’ll have to think about how you use your power.

For folks like me, simply looking to buy at a cheaper rate to use when power is more expensive, any capacity will benefit you. But if you have a cheap six-hour rate overnight, for example, then you ideally want it to last for the other 18 hours. It makes sense to get as much as you can up-front because the installation costs are high. Even adding to modular systems later often requires professional installation to avoid voiding your warranty.

Do You Need Upgrades or Permission?

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.

  • Depth of discharge: This is how much of the battery’s capacity you can safely use without damaging it.
  • Efficiency: This is the percentage of the power you put into the battery that you can actually use, because some energy is always lost in the storage process.
  • Warranty: This is a guarantee about the minimum performance you can expect before a battery degrades (they all degrade over time), and it’s often stated in years and charging cycles (whichever comes first). For example, EcoFlow promises at least 70 percent capacity after 15 years or 6,000 charging cycles.

How Much Home Battery Do You Need?

It can be tricky to calculate how much battery capacity you need, and it depends on your use case. If you want to guard against outages or live off-grid, you must consider how much power you use over time and also the sum of your maximum power usage at any given moment to ensure your capacity in kWh and output in kW are enough. If the output is not high enough you may not be able to run power-hungry appliances at the same time, so you’ll have to think about how you use your power.

For folks like me, simply looking to buy at a cheaper rate to use when power is more expensive, any capacity will benefit you. But if you have a cheap six-hour rate overnight, for example, then you ideally want it to last for the other 18 hours. It makes sense to get as much as you can up-front because the installation costs are high. Even adding to modular systems later often requires professional installation to avoid voiding your warranty.

Do You Need Upgrades or Permission?

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.
