Waymo received approval Friday afternoon from the California Public Utilities Commission to operate a commercial robotaxi service in Los Angeles, the San Francisco Peninsula and on San Francisco freeways.

The approval removes the last barrier for the Alphabet company to charge for rides in these expanded areas. Importantly, it opens up new territory for Waymo in one of the country’s largest cities and unlocks a route to San Francisco International Airport, which is located south of the city.

Waymo has operated a commercial service 24 hours a day, seven days a week throughout the city of San Francisco since receiving approval from the commission in August. Waymo is also allowed to give people free driverless rides in parts of Los Angeles. But until today’s approval, it was not able to charge for rides in Los Angeles.

In today’s column, I am continuing my ongoing coverage of prompt engineering strategies and tactics that aid in getting the most out of using generative AI apps such as ChatGPT, GPT-4, Bard, Gemini, Claude, etc.


A new prompt engineering technique indicates that mentioning Star Trek when prompting in generative AI can be beneficial. Read about the Spock-like logic involved.

Li Auto, a Chinese EV automaker, has just unveiled the 7-seater Mega.


Li Auto, a Beijing-based automaker, has just unveiled what it has called the world’s biggest electric vehicle (EV). Called the Mega, this is tailored towards large family consumers in China (the world’s most crowded car market).

And the Mega certainly lives up to its name. 17.5 feet (5.35 meters) long, 6.44 feet (1.965 meters) wide, and 6.1 feet tall (1.85 meters), the Mega has a wheelbase of around 10.82 feet (3.3 meters). The vehicle has seven seats set within a plush and spacious interior.

Even so, proponents say that TMS and other noninvasive brain-stimulation methods—which include updated forms of electroconvulsive therapy (ECT) and transcranial direct-current stimulation—have yet to achieve their full potential, both as research tools and as clinical treatments for a range of neurological conditions. To get there, researchers want to fully understand the biological mechanisms behind these techniques, along with finding more rigorous ways to test them in the lab, all with a view toward making treatments more tailored and reliably successful. With its demonstrated benefits and lack of serious side effects, Colleen Loo, a neurostimulation pioneer at the University of New South Wales, says, “there’s no reason TMS can’t be used as a frontline treatment” for major depression.
