I think sol ring and mana crypt are so comparable id have to go with sol ring just to maintain the whole alpha thing

i joke but it genuinely really hurts to watch the game that in many ways saved my life a decade ago turn into a case study for everything that's bad about corporate art and intellectual property

My whole group chat is mourning competitive magic and trying to quit but I'm so glad magic is making more money than ever.

Charlie Kirk was a man of violence. He cheered for violence, he helped create violence. He used violent rhetoric to inspire others to violent actions. He spent his time on this earth making it a more hateful, violent place. I do not consider it especially shocking that he met a violent end.

I need Democratic online types to understand that because of this, Newsom is dead to me. Dead. I'd sooner vote for an actual corpse. There is no hope, none, that he'll win me over, *because he has established he is a bad person*. There's no coming back from this. Take my advice and move the fuck on.

Oh we are nowhere close to AGI and it doesn't have to do with costs, it has to do with the models themselves. The models don't think. They don't 'learn' in the sense that we do. They *can't* grow. They're just the worlds most sophisticated matrix multiplication systems.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
Right, and I'm saying I think you're wrong, with the smart money. The problem is, whether or not it can be done, I think its close to 0% for anyone to actually try to do it. There's simply no money in it. Magic doesn't have the same allure to it like league or history to it like chess.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
yeah basically. The question isn't can it be done. It can. the question is, can you get the right people on the problem and can you secure the funding to do it.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
granted, the question we're trying to solve isn't optimal play, its 'better than a human'.

I don't think magic is precisely quantifiable actually: arxiv.org/abs/1904.09828

Magic: The Gathering is Turing Complete
$\textit{Magic: The Gathering}$ is a popular and famously complicated trading card game about magical combat. In this paper we show that optimal play in real-world $\textit{Magic}$ is at least as hard...

Actually I think this would be the most difficult part about building an AI model for magic; you'd need to build a simulation engine to perform the reinforcement learning, and uhhhh. It can be done I guess. but man I wouldn't wish to be the one in charge of that

Sarah Shearing @sshearing.bsky.social · 19/08/2025
my point was that its explicitly not solvable, and even though there is mathematical structure to language, no one actually uses any of it when building these models.
110
Sarah Shearing @sshearing.bsky.social · 19/08/2025
I would agree that LLMs don't beat humans at language in general, but when broken into smaller tasks, models often outperform humans now (e.g. a model can outperform humans on translations consistently, or summarization). I just brought up language as its my area of expertise.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
The outcome is often just a new position that is favorable by some reward metric. It might be computing 5-10 positions deep, but that's an infinitesimally small slice to all the future positions possible.
100
Sarah Shearing @sshearing.bsky.social · 19/08/2025
I think there's a misunderstanding about what the outcomes here are. The machine isn't taking some input position and computing every possible future position from that and determining which wins and loses. Because that's not computable.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
like one layer activates mostly on numbers, or quotes. Or another mostly on prepositional phrases. But that's an oddity. In general, none of it is human readable in any sense, and whatever the model 'learned' in its weights is a complete black box
000
Sarah Shearing @sshearing.bsky.social · 19/08/2025
There's no module for syntax, or word order, or structure of any kind. We just build absolutely enormous models and then throw all the data we can find at it and let it learn or discover any structures on its own. You'll often find layers that seem to do something specific to a human
200
Sarah Shearing @sshearing.bsky.social · 19/08/2025
but like, for example, we build neural networks for language. They translate, summarize, etc. But, as someone who builds language models for a living, the current state of the art doesn't actually utilize anything about the structure of language
110
Sarah Shearing @sshearing.bsky.social · 19/08/2025
I would need to know how you understand neural networks to work I guess. But for the most part, neural networks as a whole aren't solving problems; they approximate them. That's kind of the whole shtick with optimization algorithms (and neural networks are optimization algorithms).
120
Sarah Shearing @sshearing.bsky.social · 19/08/2025
Right, but whether or not its mathematically solvable doesn't actually have any bearing on the models we're using, because for all practical purposes they aren't solvable. So we use approximation / optimization / learning algorithms instead, which are the same algorithms I'd start with for magic.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
One counterpoint to this though is that specifically MOBA games, like Dota and League, AIs are not *currently* able to beat the best players consistently. I'd have to look into the literature to see where the state of those AIs left off though, I am not completely aware of all the work done there

Sarah Shearing @sshearing.bsky.social · 19/08/2025
For games with hidden information, you can look at for example starcraft (fog of war). I'd have to look up further for other games. I know rocket league was competitive but not necessarily always better.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
I mean, chess. Chess isn't actually solvable. There are more possible chess positions than there are atoms in the universe. You cannot build a model that 'solves' chess in the sense that it can know every possible outcome. Go is even worse (10^700 I believe vs 10^20 for chess).

Sarah Shearing @sshearing.bsky.social · 19/08/2025
and when I say enough times, I'm talking billions of simulations. More simulations than the total games of magic humans have played.
000
Sarah Shearing @sshearing.bsky.social · 19/08/2025
Reinforcement learning loops don't require you to have perfect knowledge of outcomes. You can simulate outcomes. Simulate *enough times* and the model will learn what actions to take that maximize desirable outcomes
100
Sarah Shearing @sshearing.bsky.social · 19/08/2025
Because we've solved equally difficult problems. Magic isn't actually all that more complex than 'solvable' games. It simply has an additional layer of unknown information. Fortunately, you can still build the same models that take unknown information into account.

Now, alpha go was 2017. So hardware should be cheaper? Unfortunately, not really. With the crypto boom, even old hardware maintains its price. So right off the bat, you have to ask: what motivation does anyone have to actually go and spend that kind of money on this?
000
Sarah Shearing @sshearing.bsky.social · 19/08/2025
Take for instance Alpha Go. The hardware alone to host an Alpha Go system costs around 25 million dollars. To actually run that hardware to train a model is an order of magnitude higher. Add in development costs, and we are easily 9 figures in terms of price.

Sarah Shearing @sshearing.bsky.social · 19/08/2025
I've had this discussion before but basically, the only reason there isn't some AI that beats people at magic consistently is because *its incredibly expensive to build*. But we already know how to do it.

Sarah Shearing @sshearing.bsky.social · 10/08/2025
Yeah its already set up and ready

Saw this from Tumblr and it really resonated with me. If you engage with/talk a lot about HP stuff, you can and should do better. I don't think people realize how much referencing this stuff continues to give her power and makes the trans people around you uncomfortable.

I am pumped for no one. There will never be a UB set i want. I thought FF was one of the worst magic sets ever because it was all so disconnected and the cards look straight up bad. But fuck me i guess, magic just isnt for me anymore
000
Sarah Shearing @sshearing.bsky.social · 25/07/2025
I hate all UB equally. Every UB set except maybe LOTR is a stain on magic. With the exception of high fantasy IP, UB just does not look like magic (which is why LOTR gets a pass. Though it also didnt need to happen).

I guess I will continue not to play legacy. I really really wish they were more willing to remove things from the format, I get the feeling they don't want to ban things for players sake in regards to $ but I think the format is worse for it and the player base is shrinking which feels much worse

Overall, I like it a lot. If you’re going to have very few windows, use them aggressively in ways that actively values changing play patterns!

gonna post a bunch of thoughts on the legacy B&R. I think the most important note to keep in mind is legacy in 2025 is inherently a casual format. There are competitive events, but it is a format defined by casual interest. Without weeklies and paper play, legacy dies. This B&R ignores this fact.
