Tanay Jaipuria: “At a high level, here is how Twitter’s algorithm works: Retrieval: Twitter’s algorithm fetches the ~1500 “best” tweets total for a given user in a given session across multiple sources. Ranking: It then ranks those tweets using a machine-learning model. Filtering: It then applies a few heuristics and filters to remove things you’ve blocked/muted/seen. Mixing: Lastly, it mixes in a few promoted tweets and other Twitter units (that aren’t organic tweets).”
WSJ: “We are fast approaching a time when “centaur doctors,” combining the best parts of human intelligence and AI assistance, will be empowered to make bold medical decisions with far fewer unintended consequences. That’s vitally important, because medical mistakes account for about a quarter of a million deaths annually in the U.S. alone. It is not an exaggeration to say that AI-enabled healthcare already has saved countless lives…In the end, we suspect that AI will be like aspirin: We will use it because it works, even if we don’t fully understand it. It will take a leap of faith, but innovation often involves venturing into the unknown for a time before it finally becomes known.”
Allan Meltzer: “Capitalism’s edge was in putting many minds to work with the freedom to innovate, protected by the rule of law to protect personal and property rights, in place of a small group of planners.” [via CafeHayek]
GQ: “[Tim Cook] is not a leader who is drawn to crisis or conflict, two climates his predecessor, Steve Jobs, seemed to at times thrive in. “I try not to let the urgent take over the day,” Cook says. Regular meetings, different standing engagements with different parts of the company. He likes to ask questions. “I’m curious, and I’m curious about how things work,” he says. He does this not to intimidate, though there is perhaps a standard, an expectation of those working for him, lurking there as well: “If something’s really shallow, you find that people can’t explain it very well.” Like Jobs once did, he sometimes takes meetings on the move, walking around the campus. Most days, he leaves the office at 6:30 or 7 p.m. The overall sensation he attempts to impart is one of normalcy, of proportion, despite the fact that most days, Apple, which employs about 165,000 people, is the most valuable company in the world.”
