Yes, semantics — what do things mean, exactly? — is the subject of the discussion here and is actually quite important in general.
I was running Stable Diffusion on my iPhone two years ago. You can get quite good open weights models running on-device today. What’s going on over there?
<example> <user>how should recent semiconductor export restrictions affect our investment strategy in tech companies? make a report</user> <response>
Finding out where the user works is in response to an under specified query (what is “our”?) and checking for internal analysis is a prerequisite to analyzing “our investment strategy”. It’s not like they’re telling Claude to randomly look through users’ documents, come on.
Actually, “we”, collectively, do know, because the SEC maintains an “XKEYSCORE for equities” called CAT.
If there was interest, the government could know exactly who placed these trades. But the call (options) are coming from inside the house.
After 8 years of programming ~exclusively in Rust it’s easy for me to take this for granted by forgetting that linker errors even exist — until I am rudely reminded by occasional issues with C/C++ code that ends up in the dep tree.
This property is downstream of the orphan rules, and given the benefit I wouldn’t give them up.
Clearly some people do find them useful.
Hmm, I wonder if the worldcoin team also thought of that possibility?
(Yes, they did, the iris processing is done inside a hardware enclave so that the obvious attack is not possible)

I am broadly anti-Worldcoin but it is reasonably competently executed at a technical level. It would be good to understand what they actually did before declaring it to be impossible.
Looking at https://eprint.iacr.org/2018/392.pdf , it seems like:
- Intel CPUs can use AESNI to do AES at 0.64 cpb - AMD Zen cores have two AESNI cores and can achieve 0.31 cpb - Vectorized AES instructions (supposed to ship in Ice Lake five years ago, but maybe a casualty of Intel's AVX512 mishaps) were expected to bring it down to 0.16 cpb
In some sense this isn't a "fair" comparison in that it's fast because there's hardware acceleration, but that doesn't really matter, the hardware is there so it might as well be used.
