Lyft just built a better e-bike for urban sharing

In pre-COVID-19 times, I worked in downtown San Francisco and was surrounded by people pedaling around on Lyft e-bikes—and never paid them much attention or gave serious thought to getting on one myself. Then a funny thing happened:  I bought my own e-bike  to help me shake off pandemic lethargy, and found that I loved it. And since I live too far into suburbia to consider commuting to my office on two wheels, I started looking forward to using Lyft’s bike-sharing service once I returned to the city. While I was getting intrigued by Lyft’s e-bikes, the company was busy creating its next-generation model—the first one it’s designed itself, after previously using e-bikes from a company called GenZe. I got to take a spin on one of the new bikes last week; more will hit the streets of San Francisco this week in a beta test, with the official rollout starting in Chicago this fall. Over time, this model will gradually replace Lyft’s current e-bikes, which comprise anywhere from 20% to 100% of its fleet depending on the market. (Between electric and conventional bikes, Lyft is the largest bike-share operator in North America.) For Lyft, designing its own e-bike started with assembling the necessary talent, which operates out of a workshop—warehouse in San Francisco and uses the environs as a proving ground. “We built this really amazing world-class design team that is passionate about micro-mobility and has a wide background from consumer electronics and everything with wheels,” says head of industrial design Oli Mueller, whose own résumé includes four years of experience working on smart-home products at Nest. The goals of this team did not include reinventing the experience of using one of its bikes in a way that might flummox current happy customers. So even though the new bike is new from the ground up, it doesn’t feel  that new. “When you take a step back, it looks kind of the same, kind of different,” says Gary Shambat, Lyft’s product lead for bikes and scooters. “And that’s purposeful.” Lyft’s new e-bike aims to be a lot better than its old e-bike, without being a radical departure.

They relate more to eliminating obstacles that might prevent people from using a bike—because it doesn’t fit them, can’t accommodate their stuff, or is just plain out of service. For example, the new bike’s seat can be lowered by an additional three inches—using a more accessible unlocking mechanism—which is a boon to shorter riders. The front-mounted basket’s backside is now closed rather than open—which should lessen the chances of your possessions taking a tumble—and its strap has been redesigned to facilitate securing bulky items such as groceries. There’s a new monochrome screen, but its primary purpose is to display helpful information before and after a ride rather than to do anything that might be distracting in transit. And Lyft learned from its experience with its current bikes to address problem areas that require e-bikes to be taken out of service for repair. Instead of a battery mounted externally on the downtube, the new bike sports one embedded inside the tube. Beyond the more elegant look, the battery has doubled in capacity from 500 watt-hours to 1,000 watt-hours—enough juice, Lyft says, for up to 60 miles of range, depending on factors such as the rider’s weight and how many hills the bike climbs. Not that any individual is likely to go anything like that distance; typical trips are more like a 1.5 to 2 miles. But the bigger the battery, the less often it needs to be charged, increasing a bike’s availability Read More …

How a largely untested AI algorithm crept into hundreds of hospitals

L ast spring, physicians like us were confused. COVID-19 was just starting its deadly journey around the world, afflicting our patients with severe lung infections, strokes, skin rashes, debilitating fatigue, and numerous other acute and chronic symptoms . Armed with outdated clinical intuitions, we were left disoriented by a disease shrouded in ambiguity. In the midst of the uncertainty, Epic, a private electronic health record giant and a key purveyor of American health data, accelerated the deployment of a clinical prediction tool called the Deterioration Index . Built with a type of artificial intelligence called machine learning and in use at some hospitals prior to the pandemic, the index is designed to help physicians decide when to move a patient into or out of intensive care, and is influenced by factors like breathing rate and blood potassium level. Epic had been tinkering with the index for years but expanded its use during the pandemic. At hundreds of hospitals, including those in which we both work, a Deterioration Index score is prominently displayed on the chart of every patient admitted to the hospital. The Deterioration Index is poised to upend a key cultural practice in medicine: triage. Loosely speaking, triage is an act of determining how sick a patient is at any given moment to prioritize treatment and limited resources. In the past, physicians have performed this task by rapidly interpreting a patient’s vital signs, physical exam findings, test results, and other data points, using heuristics learned through years of on-the-job medical training. Ostensibly, the core assumption of the Deterioration Index is that traditional triage can be augmented, or perhaps replaced entirely, by machine learning and big data Read More …

Google’s plans to bring AI to education make its dominance in classrooms more alarming

When Google CEO Sundar Pichai addressed the company’s annual I/O Developers Conference on May 18, 2021, he made two announcements suggesting Google is now the world’s most powerful organization in education. Opening the livestreamed keynote from the Mountain View campus gardens, Pichai celebrated how Google had been able to “help students and teachers continue learning from anywhere” during the pandemic. Minutes later, he announced Google’s new AI language platform, a central part of the company’s long-term AI strategy, with a specific use-case example from education. LaMDA (Language Model for Dialogue Applications), he claimed, could enable students to ask natural language questions and receive sensible, factual, and interesting conversational responses. “So if a student wanted to discover more about space,” Pichai wrote on the company blog , “the model would give sensible responses, making learning even more fun and engaging. If that student then wanted to switch over to a different topic,” he added, “LaMDA could continue the conversation without any retraining.” The company plan is to embed LaMDA in its Workspace suite of cloud computing tools, software, and products. These proclamations indicate how Google plans to advance its business in education following the disruptions of COVID-19—by consolidating the huge growth of its platforms in schools and integrating AI into teaching and learning. That’s raising fresh concerns among privacy campaigners and researchers because it gives Google access to data about students and schools at international scale. Google’s global classroom With schools reopening worldwide, Google has worked hard to ensure the big market gains it made in 2020 can be sustained and strengthened as students return to physical rather than virtual classrooms Read More …
