*distributes the purse

You are correct- the order has no authority outside of the Federal Government.
Within the Federal Government, it has the effect of setting up a goon squad to track down any reason they can find to sue and take money away from States that don't comply.

He has no authority to preempt State law, only Congress does.
But as he has demonstrated with his university funding antics- he doesn't really need the authority.
His newly granted power of the guy who distributes the purpose is authority enough for just about anything he wants to do.

I'm quite familiar with the 10th Amendment.

It is at this point that I point out that you have not read the order.
Do you know how I know you didn't read the order? Because nothing in it contravenes the 10th Amendment.

Any time someone challenges you after you've done nothing but read a headline, the first thing you should do is actually try to learn about the topic you're diving into an argument on.

The order does not take any power from the States. It doesn't even assign any kind of new power to the Executive. Congress won't even need to sign off on this.

What the order does, is orders the Federal Government to vigorously look for problems in any State AI laws, and sue the States wherever problems in those laws are found.
It then further directs agencies to withhold money from the States until they are in compliance with the ordered "AI Policy".
The entire thing is some mob boss shit, but if you question its legality, all you need to do is look at what he's been doing to Universities. It's the same tactic.
If you can't order them to do what you want, take away your money until they make the decision for themselves.

Preemption doesn't even apply.
The order also does nothing of the sort.
It just threatens Federal retribution wherever the Federal Government can can find the means if the State doesn't follow the policy.

It's pretty clever, really. There's no way for a state to fight the order. The order is just a direction to the government to find things to harass the State for.

It's far from a no-op.
You misunderstood the point of the EO.

They're not going to sue the State because the AI law contradicts the policy set forth within the order, they're going to sue the AI law for being unconstitutional, written on ugly paper, or whatever they can find.
Then they're going to start withholding Federal funds from the State.
You can read the actual order, here.

They can. There's no order Trump can sign to stop them legally- which is why that's not what he did. The headline makes it seem like that, but it didn't.
What it does is much more insidious. It orders the Government to engage in lawfare and withholding of whatever funds are considered legal to withhold to any state that doesn't follow the Executive policy on AI.

i.e., he can't legally order them to stop "doing something about AI", but he can take their money away until they decide it's not worth it anymore.

It's almost certainly legal.
On what grounds do you think it's illegal?

Oh- you're a doomsday preacher on the corner of Hollywood and Vine- got it.

It's a misleading headline.
The order doesn't try to "override States laws" (I said the same as you- "uhhh, that's not a Power the president has to put in the form of an order.")

What it does, is order Federal departments to throw every bit of power they have at the State if it does not play ball (Sue them for any and all things you can find to sue them for, withhold grants, etc.)

Since nobody has managed to stop him from doing this to universities, I do not suspect they're going to be able to stop him from doing it to the States, either.

Nothing to override.
What this EO does is direct the Federal Government to leverage its power in whatever ways it can (suing for whatever they can find, withholding funds, etc) if the State does not follow the Government's wishes.
It's basically the shit he's been doing with universities.

Since the order doesn't try to set some kind of regulatory rule- and just directs the Federal Government to... mmmmh, harass within the bounds of the law... I'd say it's got plenty of teeth.
I would say, "That's an interesting way to try to overstep Federal power..." if he hadn't been doing it to universities for a year now.

Common misconception about EOs going on here, I think.

You can't write an EO that declares State law null and void. That's not a power that the President has.
You write an EO to direct the Executive departments to do something.

In this case, he has ordered the relevant agencies to engage in lawfare and grant withholding to people who don't cowtow to the will expressed in the EO.
I.e., he's avoid setting a regulatory rule. Instead he's setting up a taskforce that tries to pummel the State into submission by withholding cash and suing it for anything it can think of.
Legal, but pretty fucking gross.

If you think LLMs do not hallucinate, then you are very much filling your head full of LLM hallucinations. That's not great.

You aren't wrong that prompting can improve the situation. However, even in the most rigorously defined tasks, they hallucinate.
Hell, the fucking things even hallucinate tool calls sometimes (amusing the first time you run into that in your agentic code)

And if you do, because you're NASA or some other space agency, may I recommend not using an LLM for that purpose.

Of course since you don't want to either A) have your LLM function as an parachute (very bad!), or B) have your parachute controlled by an LLM, certainly that means they're useful for everything, right?

My wife once told me that she couldn't put the TV up on the wall without help. Divorced her on the spot.

Ya, the percentage improvement is fucking annoying.
Using the dipshit's parachute model, every single parachute in existence has a probability of not opening.
38% reduction of that is universally good.

Whether or not that probability is 50%, or 0.00005% is what matters.

Europeans?

In my experience, visiting Europeans tend to be young people with no money at all.
The median American has more money than the median European, anyway.

Let's look at the real impact of a loss of Eurodollars in the tourism industry in the US.
It seems we're projected to lose ~$12.5B this year.
That's out ~$30500B.
How, oh how, will we ever survive?
Canadians are more concerning. But our neighbors up north are really only sauced over Trump treating them like they're fucking second class US citizens, and they're quick to forgive. Europeans are too busy smelling their own farts and confusing their dreams with the continuance of their relevance.

I was being sarcastic.
I use it for productive work right now.
So do many people.
The industry for people using it for work is already measured in billions of dollars per year in revenue.

If you don't- that's just fine.

This is your key insight. I'd add DamnOregonian's corollary to it, though: Not all work requires a model capable of producing superintelligent output. Sometimes-bordering-on-kinda-dumb-but-also-freakishly-skilled-in-certain-ways is also perfectly sufficient at times.
