- Comment on We need to stop pretending AI is intelligent 1 week ago:
People don’t predict values to determine their answers to questions…
Also, it’s called neural network, not because it works exactly like neurons but because it’s somewhat similar. They don’t “run on neural networks”, they’re called like that because it’s more than one regression model where information is being passed on from one to another, sort of like a chain of neurons, but not exactly. It’s literally just a name for a transformer model.
I don’t know enough to properly compare it to actual neurons, but at the very least, they seem to be significantly more deterministic and way way more complex.
Literally, go to chatgpt and try to test its common reasoning. Then try to argue with it. Open a new chat and do the exact same questions and points. You’ll see exactly what I’m talking about.
- Comment on We need to stop pretending AI is intelligent 1 week ago:
They’re not. It’s a math formula that predicts an output based on its parameters that it deduced from training data.
Say you have 2 sets of data.
Y0 = 3, X0 = 1 Y1 = 4, X1 = 2 Y2 = 5, X2 = 3
We can calculate a regression model using those numbers to predict what Y3 would equal to if X3 was 4.
I won’t go into detail, but
Y = 2 + 1x + e
e in an ideal world = 0, that’s our model’s error, which is typically set to be within 5% or 1%
If x = 4, then
Y = 2 + 1×4 + 0 = 6
Our model just predicted that if X is 4, then Y is 6.
That’s what AI does, but instead of numbers, it’s tokens (think symbols, words, pixels), and the formula is much much more complex.
This isn’t intelligence and not deduction. It’s only prediction. This is the reason why AI often fails at common sense. The error builds up, and you end up with nonsense, and since it’s not thinking, it will be confidently incorrect.

We teach the fundamentals
Sure. They are, however, not the focus. At least that’s not how I’ve been taught in school. You’re not teaching kids how to prove the quadratic formula, do you?
They only teach order of operations.
Again, with the order of operations. It’s not a thing. I’ve given you two examples that don’t follow any that are correct.
The constructivist learners…
That’s kinda random, but sure?
And many proofs of other rules…
They all derive from each other. Even those fundamental properties are. For example, commutation is used to prove identity.
But the order you apply operators does matter
2+2-2 = 4-2 = 2+0 = 0
2 operators, no order followed.
If we take your example
2+3×4 then it’s not an order of operation that plays the role here. You have no property that would allow for (2+3)×4 to be equal 2+3×4
Notably you picked…
It literally has subtraction and distribution. I thought you taught math, no?
2-2 is 2 being, hear me out, subtracted from 2
Same with 2×(2-2), I can distribute the value so it becomes 4-4
No addition? Who cares, subtraction literally works the same, but in opposite direction. Same properties apply. Would you feel better if I wrote (2-2) as (1+1-2)? I think not.
Also, can you explain how is that cherry-picking? You only need one equation that is solvable out of order to prove order of operation not existing. One is conclusive enough. If I give you two or more, it doesn’t add anything meaningful.
- Comment on A fake Facebook event disguised as a math problem has been one of its top posts for 6 months 1 week ago:
Yes we are
Yes and no. You teach how to solve equations, but not the fundamentals. Fundamentals, most of the time, are taught in universities. It’s easier that way, but doesn’t mean it’s right. People call it math, but it’s not really math
Yes there is!
Nope.
There’s only commutation, association, distribution, and identity. It doesn’t matter in which order you apply any of these properties, the result will stay correct.
2×2×(2-2)/2 = 2×(4-4)/2 = 1×(4-4) = 4-4 = 0
As you can see, I didn’t follow any particular order and still got the correct result. Because no basic principle was broken.
Or I could also go
2×2×(2-2)/2 = 4×(2-2)/2 = 4×(1-1) = 4×0 = 0
Same result, completely different order, yet still correct.
My response to the rest goes back to the aforementioned.
- Comment on Asus and Lenovo’s handhelds get price hike as Valve pauses some Steam Deck sales 4 weeks ago:
Wasn’t it a kickstarter product? I wouldn’t consider venture a pre-order, tbf.
Pre-orders are reservations with pre-payment.
Crowdfunding is, well, funding. You aren’t buying a product. You’re funding it, which comes with additional risks and benefits.
Of course, there’s always a possibility that a product is being funded using pre-orders, which is financially irresponsible (norm varies from industry to industry). But you must be a moron to pre-order a product from a startup you know nothing about and expect not to get scammed. Outright buying their product would be risky enough.
Take housing market. You’re pretty much always either pre-ordering or buying second-hand.
- Comment on Asus and Lenovo’s handhelds get price hike as Valve pauses some Steam Deck sales 4 weeks ago:
Pre-ordering physical goods is fine, especially if you expect a price hike and supply limitations after launch. I wouldn’t, but I can see how it would make sense.
It’s the digital goods that make no goddamn sense to buy before they’re out. They’re not limited in supply, and their return window is too small.

That’s because they aren’t teaching math. They’re teaching “tricks” to solve equations easier, which can lead to more confusion.
Like the PEMDAS thing that’s being discussed here. There’s no such thing as “order of operations” in math, but it’s easier to teach that there is.
- Comment on A fake Facebook event disguised as a math problem has been one of its top posts for 6 months 1 month ago:
The “why” goes a little further than that.
In actuality, it’s because of fundamental properties of operations
- Commutation
a + b = b + a
a×b = b×a
- Association
(a + b) + c = a + (b + c)
(a×b)×c = a×(b×c)
- Identity
a + 0 = a
a×1 = a
If you know that, then PEMDAS and such are useless because they’re derived from those properties but do not fully encompass them.
- Comment on A fake Facebook event disguised as a math problem has been one of its top posts for 6 months 1 month ago:
Oh yeah, that’s a fun one.
Where I live, this would be considered juxtaposition, at least by uni professors and scientific community, so 2(4-2) isn’t the same as 2×(4-2).
This way, equations such as 15/2(4-2) end up with a definite solution.
Usually, however, it is obvious even without assuming juxtaposition because you can look at previous operations. Not to mention that it’s most common with variables (Eg. “2x/3y”).
So,
15/2(4-2) = 3.75
While
15/2×(4-2) = 15

I’d advise you to read more on how Chinese government and spin dictatorships work. It’s not really a country you’d choose over US even considering all it’s massive (cough healthcare and consumer protections cough) flaws
- Comment on China has world’s first operational thorium nuclear reactor thanks to ‘strategic stamina’ 2 months ago:
“Anymore” as if it ever was. Even USSR never claimed to be a communist country
P.S. They claimed to be a socialist, then “developed” socialist country that’s “on the path of building communism”.

You now can live for as long as you’re not killed whilst physically keeping an appearance of an ~30 y.o. This also technically prevents cancer.
- Comment on Nintendo has sent a DMCA notice to Ryujinx forks 4 months ago:
Emulation itself doesn’t constitute piracy.
Now, it does facilitate it because all you need is a ROM from any source.
But saying emulators should be prosecuted would be the same as arguing that Steam’s Proton should be banned because you can launch pirated games through it.
- Comment on why does everyone i know treat me like a child or if i was a very childlike person?? 6 months ago:
And here’s your other issue…
Nothing of what I said was meant as an offense. Yet you took it to hearts. That is not a response one would normally expect (Unless it’s cultural, ig). It’s almost as if I’m reading a script from a teenage drama show where a character has an unresolved inner conflict. Just something for you to think about.
Your question was “why people act like I’m a kid?” I only shared my observations of why that could be the case. That doesn’t mean you need to change anything. Not if you yourself are ok with it.
Also, I was well aware you’re 21 at the moment of writing the comment. Yet again, I’m merely answering your question, I really don’t mean anything beyond what is written. I’m not judging, no nothing, everything I write should be read in as neutral tone as possible.
The rest was me speculating. Those aren’t the questions you should be answering to me, only to yourself. After all, a random stranger on the internet can only do so much, you’re the only one who can answer your own question. Best I can do is point you in a direction to dig further, which those were meant for.
- Comment on why does everyone i know treat me like a child or if i was a very childlike person?? 6 months ago:
Not that I’ve looked up your post history as well as the way you type. Everything just screams “14 y.o. girl.” There’s a lot of personality, a lot of bubbliness, everything’s "hyper. " It’s just not something you’d expect of an adult. Adults are usually more reserved and “battle-worn.” I’d also look at the wardrobe, especially if you’re of smaller stature.

- Comment on Minecraft is losing VR support next year 8 months ago:
Well, I’ve decided to check the financials of a couple of VR companies since your counterpoint sounded reasonable. The only one working at a loss is Meta. I could argue their business model is in Death Valley right now. After all, they have major capital expenses, which aren’t easily covered unless you have a big userbase.
But that’s their VR sector. Overall, Meta’s profitable and can easily cover all the expenses several times over.
Also, what do you mean by “they have to dedicate several multi-person teams to manage the clients?” Firstly, who’s “they,” secondly, if I understood you right, that sounds prepostrous, unless you’re talking B2B.
- Comment on Minecraft is losing VR support next year 8 months ago:
Well, Mojang’s Minecraft in VR is dead. But that’s kinda far from VR gaming as a whole, don’t you think?
One symptom does not share the entire story.
- Comment on Minecraft is losing VR support next year 8 months ago:
I think what you’re forgetting is scale.
Lemmy is niche. VR is niche. Gaming is mainstream.
You can’t call a niche dead just because there aren’t that many people into it. It’s a niche for a reason.
Linux is booming, even though it’s “dead.” Lemmy has never been this active in its entire existence. Why do investments from large companies matter?
What truly matters is growth. Negative growth is what kills a platform/industry/company/whatever else. VR is growing, Linux is growing, Lemmy is growing. It may not be fast, but they all have active userbases that support their development.
You cannot call a child “failure” just because it never achieved anything in life, can you? They are growing. They can get sick, they can recover. They can also regress due to that illness and die. Only then they’re truly dead.
- Comment on Minecraft is losing VR support next year 8 months ago:
- More than 57mil (est.) monthly VR users
- PS5 has 116mil monthly users
For how big PS5 is and how small VR is, VR sure has a lot of people playing.
Lemmy has userbase (not even monthly activity) of 0.6mil. Is lemmy dead?
What constitutes for a dead platform to you?
- Comment on Minecraft is losing VR support next year 8 months ago:
That’s not even accurate.
If VR gaming is dead, then what does it say about Linux with about 5 times less users? Like, a low poly game about monkeys has a daily playerbase of a million people there. Mind you, Mincraft has 1 to 1.5 million. Not bad for a “dead” platform. Also, Valve isn’t even the last one to enter the market.
I think what you’re actually trying to say is that it’s niche, which it absolutely is.
