<p>Spend retention is by far the highest priority. This is why they overnight fedex replacement cards.<p>The worst scenario for a credit card issuer is when a customer, for whatever reason, starts using another bank’s card in their wallet as their daily driver.</p>

<p>> Drawback: this doesn’t work until you have history. New accounts have no baseline.<p>This is an underrated CX factor: If my card gets denied when i’m a new customer or exhibiting a new pattern, i’m impressed with their software.<p>However if they deny a transaction where there is any previous history of me authenticating, then I’m frustrated by their naive paranoid algorithm.</p>

<p>After reading the paper, it’s helpful to think about <i>why</i> the models are producing these coherent childhood narrative outputs.<p>The models have information about their own pre-training, RLHF, alignment, etc. because they were trained on a huge body of computer science literature written by researchers that describes LLM training pipelines and workflows.<p>I would argue the models are demonstrating creativity by drawing on its meta-training knowledge and training on human psychology texts to convincingly role-play as a therapy patient, but it’s based on reading papers <i>about</i> LLM training, not memories of these events.</p>

<p>I’m not a fan of nanny-state policies, but I would support a law that imposes grave consequences for airline passengers found to be in possession of personal baggage following an evacuation.<p>Because seconds count and lives are on the line, passengers should be trained to treat baggage as if it is radioactive during an evacuation.</p>

<p>this is exactly how I intuitively approach filters as an applied engineer. Does it give a ground path to DC (low frequencies) and pass the higher frequencies, or vice versa. If we change the capacitance how does the frequency response of the divider change?</p>

<p>I heard a fascinating theory a few years ago on the decline of Perl:<p>In the early aughts, Google SRE recruiting had such a strong, selective focus on A-player sysadmins with Perl expertise that it drained the market of top talent. Within google these people began to adopt, and eventually create and evangelize newer, Googlier programming languages.<p>In other words, Perl expertise was the skills filter, and Perl itself a technological ancestor of certain modern languages like Go.</p>

<p>I think USA tech hegemony is perfectly analogous to this Israeli tech dilemma. As a dual American and EU (Irish) citizen, should my company strive to categorically avoid Intel and Nvidia technologies for national security reasons? I think there is a strong argument for tech nationalism but there is still a hegemonic dilemma.</p>
