That is what Jane Street (IIRC) was accused of. Some of its traders then went to another hedge fund and did the same trick there, reducing Jane Street's profit, and ended up being sued by Jane Street. (BTW, Jane Street claims it was not manipulation, but basis trade arbitrage.)

Of course, 9 out of 10 gambler end up in the red.

1) Imagine pushing the boat down into the lake, displacing water. The level would go up.

2) Imagine the ball instead of being in the boat, is attached under the boat by a rope. Same thing. (Imagine it magically moving through the bottom of the boat - it has no impact on the boat or water level).

3) Imagine you cut the rope. The ball will fall, and the boat will bob up. Water level goes down.

If you want to argue that bonds and stocks have become more correlated, sure, but we do not know what hits us next.

If you put all in at a certain price, and later the market moves down, you'll regret that you didn't buy cheaper, and think you timed it badly.

If, however, you commit to a strategy of putting in say 5% per month over the next months, then a) you just automate it, and don't think about it anymore, and b) you don't really have a reference price at which you bought (sure, you can determine your actual cost basis, but who does that...) and thus avoid regret when the market tanks. Plus you reduce variance (by reducing the variance of your cost basis).

Dear Colleagues,

This is a historic moment in cryptology: AI has beaten humans at cryptanalysis. We would like to share a few thoughts with the PQC community based on our own experience.

There are other dimension-reduction attacks on HAWK in literature. At Eurocrypt 2026, we proposed a dimension-halving algorithm for quaternion Ideal-SVP, which potentially implies that HAWK-n key recovery can be reduced to (cyclotomic) Ideal-SVP in dimension n:

Later, we proposed another guessing attack based on advanced number theory, under a few heuristic assumptions:

https://eprint.iacr.org/2026/1318

However, one of these heuristics was soon found to be invalid by colleagues with the assistance of AI.

Apparently, we were outpaced by AI in both cases. A couple of lessons we have learned are: (a) humans can make mistakes; and (b) humans are slower than AI. Beyond cryptanalysis itself, the use of AI to check mathematical proofs is becoming an increasingly serious issue.

One can even imagine a crisis in cryptography: in the worst-case scenario, all human-designed cryptosystems are broken by AI. Whether or not that happens, a new era—Post-AI Cryptography—has arrived.

No. Apple provides an API, but Apple doesn't ask for reviews. The app has to initiate the process to ask for a review (through Apple's API). That is what the developer highlights: If Apple were to solicit reviews from customers, then said API could be retired and apps could reasonably be banned entirely from soliciting reviews. As it stands, they're caught in a tragedy of the commons, with unscrupulous developers winning (e.g. with fake reviews, or the annoying "are you satisfied" pop-up before displaying the Apple API).

Interesting. Apps can only ask three times a year (from Apple's documentation, my highlights):

"Asking for ratings and reviews

You can ask users to rate and review your app at appropriate times throughout the user experience. Make the request when users are most likely to feel satisfaction with your app, such as when they’ve completed an action, level, or task. Make sure not to interrupt their activity. The SKStoreReviewController API lets you give users an easy way to provide feedback about your app. You can prompt for ratings up to three times in a 365-day period."
