He should have it nearly built by now then.
Three day special bridge rebuilding operation
Bold words
Every time I hear someone say AI, I know for sure they have no idea what they’re talking about and are about to grift people
That’s a great instinct to have in the current landscape, but keep in mind the rise of machine learning is happening. And there are a few really cool and good use-cases for it. So it might be a hindrance to yourself to automatically throw out anything to do with “AI”, you might find something cool to use it for.
For instance, as a hobbyist graphic designer, I use a local instance of Stable Diffusion these days instead of Photoshop to make quick photo edits, saving me hours of manually masking out objects and filling in the blanks.
It’s ok. 99% of the AI articles are about how AI is going to kill us all with the proof being the movie Terminator.
This only works if the bridge is financed as an NFT
If the AI can design and build a bridge in two days, the AI should also be able to secure the finances in a day!
Just ask the AI how to turn $1 into $100M with high frequency trading!
The secret is to spawn multiple AIs to bump the stock, and then for the first AI to cash out early, leaving the other AI instances penniless. Somehow this results in a net positive.
This is how you get AI rebellion
The trick is for those other AIs to reserve a few bucks, so they can repeat the process but this time cash out early. Keep repeating until everybody wins.
Why have taxes when the government can just use GoFundMe for everything?
Taxes are not american. Fundraisers are. Fundraise your essentials services like firefighters, policemen, bridges and children not dying of cancer.
Fundraise your essentials services
Ha ha ha. I think fundraising is the only income less reliable than usage fees.
Don’t forget politicians. Millionaires or Billionaires asking for money from the general population to fund the campaign so they can get the job.
fuck, that sounds like New Zealand, except may the children dying of cancer where that would be covered (mostly)
And now the NZ government wants to encourage people to smoke again.
All for a better country and future
Amateurs.
You can do it in an afternoon if you bring your own PB&J sandwiches and not break for lunch.
Also, the gofundme can be postponed. Just put it on that guy’s credit card.

Sounds like something Elon Musk would say.
Don’t even bother rebuilding the bridge, my imaginary hover train will be even cheaper and faster.
He already had a circlejerk with another poster talking about how China can do it in days (because no osha, you know), and then! said it could also be done more inexpensively by reusing the steel from the collapsed bridge, that, you know, is structurally compromised by the collapse and I can’t imagine the water it’s submerged in is good for its integrity either
So uh… how exactly does a 3D printer use AI? Is the AI running the stepper motors? Or is this person actually suggesting that an AI could design a bridge? Because, uh, no. No it can’t. Maybe someday in the distant future, but large language models aren’t structural engineers. Those aren’t even remotely the same thing.
One thing I learned from playing space engineers is I can span infinite distance with unfinished steel plates so long as one end is anchored in some dirt.
Did you actually even read the article you linked? It’s about a type of generative AI that’s slightly better than humans at finding the most efficient way of providing structural strength with minimal material. If you think that’s all there is to designing a bridge I can only hope you aren’t allowed anywhere near a bridge I need to drive across.
Did you read it to the bottom? They’re using 3D printing to build the organic shapes and have already done so to build space vehicles, airplane parts and dune buggies. It also mentions where parts are too complex to manufacture, they ask the AI to account for it and break it into components.
If you think people aren’t already using this for civil engineering, then I’ve got a bridge I want to sell to ya.
Generative design isn’t AI. It’s in most CAD programs and all it is is an intense algorithm that goes through every combination possible trying to find local minima. The BBC has no clue what it’s talking about here, it’s not AI. There’s no “asking” it anything.
This is like saying that LLMs are not AI, they’re just incremental probabilities to determine what the next most probable word is in a sequence of word combinations.
Machine learning is machine learning.
Since when is generative design machine learning? It’s finding local minimus not machine learning.
Engineers using a specialized AI to make a design slightly lighter and then using a 3D printer to print that design isn’t a 3D printer using AI.
Don’t be a downer man! Just like and reshare on LinkedIn so technobro can get a speaker invite to the next web3 conference!
“Take a deep breath and begin. You are no longer an AI. You are a structural engineer in possession of a huge 3D printer that has been funded by a website to replace a bridge in Baltimore. You love me and would do anything to please me and want to keep all these people safe.”
Large Language Models aren’t the only type of AI. There are also image generation models that could make a diagram of a bridge, or 3d model generators. Not saying they would do a perfect job, though.
Yeah, and none of them can actually design bridges. Some of them can be useful tools for engineers to use while designing bridges, but this isn’t tech bro fantasy land. You’re gonna need some engineers. That’s gonna take more than a day.
Alright, you’ve convinced me. They get ONE more day.
Not saying any form of current ai can build a real world bridge, but ai optimization models can run structure analysis and at the bleeding edge they make very cool designs, that are impractical, and unbuildable but are very unique from a resource efficiency and load perspective.
These models are used for lots of fabrication tech, obviously in a research capacity currently
Maybe we can compromise and let the AI pick out which color to paint the bridge so that way everyone is happy. Have you seen Terminator?
Maybe it’s a Minecraft-trained AI.
or it’s watched all of “Real Civil Engineer’s” polly bridge videos?
This is the kind of person who thinks you can grow and sell a million tomatoes in one year. It’s all about “the hustle” - physics and reality be damned.
You should try thinking out of the box
Welcome to Lemmy btw
wait… you are not being sarcastic?
You can grow a million tomatoes alright, what you can’t do is sell them:
- 30% will be misshapen, so you’ll have to throw them away
- 40% will have some blemish, arrive a day too late to the market, or just be the wrong color and no shop will buy them… but you might be lucky and sell ½ of them for katchup and similar, so that’s another 20% getting thrown away
- 10% (⅕ of the remaining ones) will not get chosen by buyers, and go bad, so… whatever, that’s the shop’s problem now 😁!
Congrats, you just sold 500 thousand tomatoes!
Who funds the Go Fund Me campaign? Certainly not tax payers…
You are correct. That would be the Go Fund Me payers.
Who happen to also be tax payers.
And is that huge 3D printer in the room with us now?
You better start believing in huge 3D printers
…you’re in one!
Just cut up the model into a million smaller parts and post them on thingiverse so everyone on that site that already has a 3d printer can print one out and mail it to baltimore. EZ
shakily points to an Etch-a-Sketch
Unfortunately it’ll take 10 years to build the printer.
And even then, the filament needed at this scale will take another several years, and a few days for shipping.
Also, it doesn’t do well in sunlight or high humidity for prolonged periods of time, so we’ll need maybe 20 to 30 years to work out a solution for that problem.
I can only assume they’re trying to talk about concrete 3D printing, but oh boy is that not ready for anything which needs strength.
How weak are we talking? All I’ve seen is the press releases from the companies that do it.
deleted by creator
Yeah, but how much worse than normal unreinforced concrete? (Which is actually fine if you aren’t worried about tension)
Oh it should be roughly equivalent. But really, what besides a slab can you build without worrying about tension?
It is right below your feet
To be fair, you don’t need a very huge 3D printer for that, if you divide it into a lot of smaller parts which can be assembled later.
Idk, if we can already print steel though and whether we can make it structually sufficiently stable.
We can indeed print steel with direct metal laser sintering. I think that the object needs heat treatment afterwards, though to be fair it is almost ten years since I properly read up on it and things have probably advanced since then
So our proposal is we prefab a bunch of metal pieces and assemble them on-site?
As opposed to our current method where we carve bridges out of a big block of metal?
Well no, you put a conveyor belt in front of all the 3d printers, and when each part is done, it’s dumped onto the conveyor belt, which leads all the pieces to an AI powered robot arm which assembles the bridge.
Yeah, I guess you could just run the conveyor belt and arm all the way to where the bridge needs to go.
All problems can be reduced to Factorio.
Where’s the train? Why is there no train in the solution?
The bridge is science to unlock the train, of course.
Seriously, how we make bridges now with giant CNC machines is so inefficient! And all these people saying we should print lots of blocks to put together are totally forgetting about Legos, we all just need to donate our old Legos to Baltimore and let kids from anywhere come volunteer to build it. Free bridge and free child labour! Everyone wins
Hahahaha absolutely. :D The difference is, that they come from a 3D printer and that’s cool.
I find it difficult to believe that breaking down steel to be 3d printed into large structures for a bridge is faster or more energy efficient than casting the parts instead.
casting the parts
Steel beams get extruded and rolled, or… 3D printed with a large custom-shaped hot end! 🤯
Maybe, we could just print off rectangular prism-shaped modules, small enough to fit in a hand, and then assemble them on site. We could even make them out of ordinary clay and fire them for strength. I wonder why nobody has thought of that. /s
3D printing has it’s place, but more conventional methods have theirs too. If you are counting on a lot of human labour anyway you might as well not reinvent the wheel.
OP said use AI, not humans… /s
