Science & Futuristic Technology

The pandemic is bringing us closer to our robot takeout future (5 minute read)

Starship is a startup that uses six-wheeled, microwave-sized robots to deliver food in campuses across the US. With a simple app, Starship now has hundreds of robots in service delivering food to real customers. The robots run at a low cost, do not require tips, and are more popular than ever as they start to displace human-driven food deliveries. For Starship to work in a city, it must create a map, get approval from city officials, sign up with commercial partners, and make sure it has enough back-end resources to support each robot. This makes its rapid growth particularly impressive as it continues to deploy robots around the world.

Social distancing in 100 square feet: Hong Kong's cage homes are almost impossible to self-isolate in (6 minute read)

Hong Kong's 'cage homes' are rooms that are often smaller than 100 square feet, with space only for a bed and some clothes. Bathrooms are mostly communal and there are usually no kitchens. Rooms are usually divided by makeshift or removable walls. It is difficult to practice social distancing. Nine in 10 people in Hong Kong live in an area smaller than 70 square meters, and yet they pay some of the highest rent and property prices in the world. As many public places are closed due to the pandemic, people who live in cage homes are suffering as they have nowhere to escape their tiny spaces. Landlords are quick to kick out tenants who are unable to pay rent, despite job losses. Hong Kong has recorded fewer than 1,050 infections and 4 deaths from COVID-19 since January.
