Right, to the actual average person, they have never heard of Grok. The average person who has heard of Grok is already on Reddit.

Grok is right there in the app stores alongside ChatGPT and Claude...

I don't think the average person has heard of Claude either.

I explained to someone who hadn't heard of it what Claude was, and they asked, "so it's another kind of ChatGPT?"

> supported primarily by xAI (Grok) Citation needed. What was the relative value of the companies before the merge?

Decent summary of it here[0]. The “space” part of “SpaceX” is valued by market analysts and money managers at around 5% of the company’s entire value. Almost all of the rest is “AI stuff”, and Twitter is a rounding error. That is, if SpaceX went back to being a space-only entity, and dropped the AI stuff, its share price should be expected to fall from $130/share to around $7/share.

There's some surprising stuff in this codebase. For example, https://github.com/xai-org/grok-build/blob/b189869b7755d2b48... is a "self-contained terminal renderer for Mermaid diagrams", which renders a subset of Mermaid chart types using Unicode box-drawing.

I had Fable 5 compile that Rust code to WebAssembly and build a browser-based playground for it, so you can try it out with Mermaid diagrams here: https://tools.simonwillison.net/grok-mermaid A few more notes on my Grok code explorations on my blog: https://simonwillison.net/2026/Jul/15/grok-build/

Thanks for doing the work and hosting this. This will very quickly become one of my daily drivers.

> Just be a rocket company

According to SpaceX's own filing documents, you are incorrect. They must be principally an AI company to justify anything close to their current valuation.

Get de-facto monopoly on American space launches and I don't think they need to be anything else.

The AI undressing scandal was on mainstream news and being discussed publicly by politicians. It's not some underground drama. The real life people I know still remember he called the cave diver a pedo after a disagreement. There's very few people left in the world not soured on Elon.

No, there's very few >left wing What mainstream news and which politicians? Cnn, Msn, Bbc? Which "scandal"? You mean that Grok Imagine had some security holes that let you "put XYZ into bikini" which were promptly patched but not before the far left and professional complainers activated their "mainstream news" co-conspirators and blown this out of proportion like they do with everything Elon related (or Trump relate…

In Europe the sales for Tesla cars drope significantly for quite a long time after Elon Musks Hitler Salute. That happened and it cost Tesla real money.

The CS stuff on Grok went through media here in germany too.

"Elon calls people all kinds of things almost every day. He's on the spectrum, we all know this, what's the big deal?"

Is this some kind of joke? You do understand that Elon Musk is not just someone and whatever you think it means that 'he is on the spectrum', he is the richest person on the planet. He literaly is responsible for satelites burning up in our atmosphere were researches just a few weeks ago mentioned that they are concered that all of that metal getting into our atmosphere could have real consequences for all of us (this is one example of many) and because Elon Musk has the 'do first accept the fallout later' attitude, he can affect all of us.

He had to buy twitter after he couln't keep his mouth shut and now he also has a big propaganda platform. You might like his right stuff more than whatever, but he changed the algorithm so that he showed up in your feed more often than he would otherwise. He also started grokpedia to 'adjust' opinions and we all know that they finetuned grok until it becamse mechahitler temporariily.

"it's what your people do."

Come on it has nothing to do with what specific people do, just look at the evidence.

And i have no clue what you mean with your floodgate. YT has not changed at all.

Regarding your other random points you try to make?

Biologiy wise science sees sex and gender on a spectrum btw. and yeah most people identify themselves as male or female. Who cares if 1% or less want to call themselves something different?

Immigration enforcement is not bad, but it makes a difference if you create a organization like ICE who kills human beings, separate kids from their parents and an overall country who accepts very cheap and illegal labor as slaves and flip flops agressivly of wanting to slaves and than wanting to throw out slaves. Especially from a country which is funded by immigrants.

Not sure about your Hamas thing, they genuin fight for freedom, plenty of actions they do are for sure not okay at all but this conflict is not about Hamas, its about Israel and Palestine people. Do you say "Hamas is bad and Israel is bad" or do you only point out some Hamas in concext of what you think is left wing politics?

The truth is that life is not that easy. Free speech is great until someone with more power missuses it. If the richest person on the planet is allowed to manipulate everyone just because they are rich and can buy twitter, this is a problem for all of us.

> since leftists often play dumb And there goes the merit of your rant

No i mean it genuinely. Right wingers are often racist and xenophobic (some have lived experience basis fot these, some not) and lately (along with leftists) quite antisemitic, lets not mince words, we know this, but leftists use deception in argumentation much more often. There's a popular hundred+ million view, often reposted and requoted, tweet about this: "It's amazing how much leftist discourse is just them pret…

I think both sides have a genuin different view of their idology.

Right wing people idology is about themselves and humans are secondary.

Left wing people idology is about all of us as a whole and humans are critical.

The right wing person wants the immigrant to go home, or want them dead but the good immigrant (their partner, wife, friend whatever) is the positive exception. You need to fight the dehuminisation of right wing propaganda so that stuff like mobs and genoicde is not happening.

The left wing person wants to help everyone and might not allow the level of individuality which doesn't allow to help everyone.

Obama was hart on immigration control but you didn't see a ICE Police who wasn't trained well, hurting people left and right.

And for generating an absolutely gargantuan amount of CSAM and non-consensual sexualized images, but yeah, exfiltrating data too.

You can't "generate" CSAM. CSAM definitionally had to be about abuse of real children. It's still bad and should be illegal but lumping them together is bad.

You do realise that saying "SpaceX are producing and distributing child porn, not CSAM" doesn't actually make things better for them, don't you?

Musk bought Twitter looking to build an “everything app,” the western WeChat. AI came along and promised an end to apps via an agentic OS that does what its user wants and vibes whatever it needs to accomplish that as it goes along. The agentic OS is basically the same thing as the “everything app,” and I doubt Musk will let go of that.

He bought Twitter to restore free speech.

He had to bought twitter because he was legaly bind after he said too much stuff.

He then leveraged his buy as a propaganda platform.

Musk itself doesn't make things. He only puts the money, and other people build the things. How many times, they need to work around him or fix his crazy ideas ? People must stop trying to compare it to Tesla or Tony Stark. He is more like the bad guy of Jurassic Park 2.

Weird how other people can put up more money and not be able to make the same things as Musk’s companies.

The people with that level of money are very few.

Payload into space is a very limited business.

This doesn't make Space-X such a high valued company at all.

And while Space-X is doing its thing, the rest of the world started to move too (china). So first mover advantage is disappearing.
