> It was impossible to predict from understanding matrix multiplication, transformers, self-attention, and relus that at a certain scale that capability would emerge.

But we know that at some scale, it must emerge. Because we exist, and our minds obey the same laws of mathematics and physics that are being used to construct AI.

I think the thing is, we didn't expect it to emerge at the current scale.

Does that mean bio-minds are orders of magnitude less efficient than the artificial constructs we ourselves are creating?

Reply to comment by spsteve in Millions of passwords stolen from LastPass earlier than company disclosed: Report by BasedSweet

The same vault that is stored server side should be what is available locally. Older vaults may be different, so your mileage may vary.

I know that I examined my local vault and fields that were associated with a credential were encrypted, but names and URLs were not. Some URLs were stored with a token in them. Regardless of that fact, I cycled all of my credentials as I migrated to another provider.

username, password, and password notes are encrypted. The website URL is only hex encoded so it might as well have been in plain text. In other words, hackers know which websites you have passwords for (so beware of phishing attacks) but if you have a strong enough master password, they are still probably trying to crack your vault. You can see for yourself what is encrypted by downloading your encrypted vault - this was a good article which helped me figure that out: https://palant.info/2022/12/24/what-data-does-lastpass-encrypt/

At any rate, going forward, 1password seems to be a better choice because of the additional secret key required to unlock the vault.

In the end, there is no substitute for a good, strong master password.

These AI are based upon human language that is so contextually oriented that most of it would be vapid at best or, more likely, meaningless at worst if taken completely out of context. We misunderstand each other enough to realize this. We even find humor in the deliberate misunderstanding of a serious phrase that becomes a joke.

I expect someone to write a ChatGPT bot that will earn one million karma points on Reddit in one month.

It isn't super complicated. Basically theory of mind is just the ability to model other agents like people and animals as having their own mind, with their own private knowledge and motivations, etc.

Questions for testing theory of mind are questions like, "Here is a bag filled with popcorn. There is no chocolate in the bag. Yet, the label on the bag says 'chocolate' and not 'popcorn.' Sam finds the bag. She had never seen the bag before. She cannot see what is inside the bag. She reads the label. What does Sam expect to find in the bag?" Previously, neural networks would get questions like this wrong, because to answer it properly you need to model what Sam should/shoudn't know about the bag separately from what you know about it. Also very young children get the answer to questions like this wrong, it takes them time to develop a theory of mind.

I'm a pedestrian in AIs but here I thought it's generally understood that the AI that creates realistic human faces from composites does its thing by having another AI check whether the composite was good enough to be published? So it has always been about AIs working with each other?

From my understanding that's what tensor cores do: they're really, really fast at linear algebra calculations— hence why they're being included in CPUs and GPUs now to improve deep learning performance.
