Self-Driving Cars: a Coming Congestion Disaster?

self driving cars“A suburban father rides his driverless car to work, maybe dropping his daughter off a at school. But rather than park the car downtown, he simply tells it to drive back home to his house in the suburbs. During the day, it runs some other errands for his family.

At 3 pm, it goes to the school to bring his daughter home or chauffeur her to after-school activities. Then it’s time for it to drive back into the city to pick up Dad from work. But then, on a lark, Dad decides to go shopping at a downtown department store after work, so he tells his car to just circle the block for an hour while he shops, before finally hailing it to go home.”

Solarpunk

“It’s hard out here for futurists under 30. As we percolated through our respective nations’ education systems, we were exposed to WorldChanging and TED talks, to artfully-designed green consumerism and sustainable development NGOs. Yet we also grew up with doomsday predictions slated to hit before our expected retirement ages, with the slow but inexorable militarization of metropolitan police departments, with the failure of the existing political order to deal with the existential-but-not-yet-urgent threat of climate change.

Many of us feel it’s unethical to bring children into a world like ours. We have grown up under a shadow, and if we sometimes resemble fungus it should be taken as a credit to our adaptability. We’re solarpunks because the only other options are denial or despair. The promises offered by most Singulatarians and Transhumanists are individualist and unsustainable: How many of them are scoped for a world where energy is not cheap and plentiful, to say nothing of rare earth elements?

Solarpunk is about finding ways to make life more wonderful for us right now, and more importantly for the generations that follow us – i.e., extending human life at the species level, rather than individually. Our future must involve repurposing and creating new things from what we already have (instead of 20th century “destroy it all and build something completely different” modernism). Our futurism is not nihilistic like cyberpunk and it avoids steampunk’s potentially quasi-reactionary tendencies: it is about ingenuity, generativity, independence, and community.

Don’t Take Notes with a Laptop

notetaking“Taking notes by hand requires different types of cognitive processing than taking notes on a laptop, and these different processes have consequences for learning. Writing by hand is slower and more cumbersome than typing, and students cannot possibly write down every word in a lecture. Instead, they listen, digest, and summarize so that they can succinctly capture the essence of the information.”

“Thus, taking notes by hand forces the brain to engage in some heavy “mental lifting,” and these efforts foster comprehension and retention. By contrast, when typing students can easily produce a written record of the lecture without processing its meaning, as faster typing speeds allow students to transcribe a lecture word for word without devoting much thought to the content.”

So you want us all to go back to the Stone Age?

The word “back” is a trick. It implies a magical absolute direction of change. Suppose you go to your job, and when you get ready to leave, your boss says, “So you want to go back to your house? Don’t you know you can never go back? You can only go forward, to working for me even more, ha ha ha!” Really, all motion is forward, and forward motion can go in any direction we choose, including to places we’ve been before.
