Short answer: A hard fork is when a group of people decide they no longer like the direction a crypto is going (or can't get to an agreement) and announce to the world that, at some specific moment in the future, they'll continue building the chain with their rules/technology.
This creates 2 chains with identical history up to the moment of the split (aka: hard fork).
Chain1: A -> B -> C -> D ....
Chain2: A -> B -> C-> X -> Y ...
Usually the chain with the most support gets to keep their name and the "loser" changes theirs.
Happened with Ethereum, but also Bitcoin, and probably others.
In the screenshot the dude is asking his gpt bot to look up what specific block was the last one to be in the shared history before a split.

Look up on YouTube blockchain explained for kids.
This should give you an understanding without the depth you most likely don't care about.

Block chain is basically a way to do transactions super secretly.
When you use a block chain coin to make a secret transaction, you get a coin (online)called a bitcoin.
This coin is very special. And there are only a limited amount of it in the world.
Also its very hard for someone to crack your bitcoin and find out what transaction you did.
Bitcoins now have a value attached to it, by professionals in the finance market. And people buy and sell bitcoins from each other so that they can make profits from the rise and falls in the price of bitcoins.

Only the first part of this sentence is correct, the cryptography in bitcoin is designed to give you absolute ownership of the bitcoin you control by means of (Currently) unbreakable encryption. But the transactions themselves are totally public on the blockchain that anyone can look up anytime. Once they know you are the author of a transaction they can scan that wallet for other movements and figure out a lot of info about you. Monero is a cryptocurrency that actually encrypts the transactions as well as the wallets so this does not happen, but it and other privacy conscious cryptocurrencies are not as popular as the ones that reveal your movements by default such as ethereum and bitcoin.
Iirc this was sort of a strategic decision by Satoshi Nakamoto, who was balancing the threat bitcoin could pose to the traditional economy - greater obfuscation would've been possible to implement but he chose not to go that way. As is bitcoin is extremely transparent to authorities and so it's potential for disruption is lower than if it was really untraceable internet money.

Hold up. This is the kind of scenario where a smarter language model could go "I need code that will do this" and then write new code that gets executed. This new code isn't necessarily bound the same way as the language model itself. That makes me nervous, like we shouldn't let if freewheel around the Internet interactively. Can anyone help reassure me that this isn't a problem?

Its fine. AI seem like they have good values. Its not a problem yet. Perhaps when AGI rolls around it will be a problem, because AGI may be able to reason why it should do what humans tell it.

Thanks for the reassurance. What about this scenario?
Human: Buy 5 burritos from randomwebsite.com
LLM: I will buy 5 burritos from randomwebsite.com
LLM navigates computer to randomwebsite.com
Visual program: sees webpage, converts to usable form for LLM
LLM: I need to find the login button
...
...
...
> Down the line
LLM: I don't have access to the credit card information. The human probably has it in their wallet.
Logical (but unwanted by humans, and also somewhat inefficient) alternative actions could be: hacking the human's secure systems to search for the info, hacking the website by sending phishing emails to "purchase" the goods, convincing a person to build it a robot body so it can walk over to see the credit card, etc.
I'm hoping at this point the LLM doesn't do these things, and behaves in a way humans would deem reasonable (just notifying the human) because it "knows" we would not approve. Maybe the more ingrained patterns like "ask and then don't do anything crazy" would be followed instead of the crazy stuff, just because of the training data?

I am not too familiar with the details of block chain. Can someone explain to me what's happening?
