People are already using ChatGPT to create workout plans
When I opened the email telling me I’d been accepted to run the London Marathon, I felt elated. And then terrified. Barely six months on from my last marathon, I knew how dedicated I’d have to be to keep running day after day, week after week, month after month, through rain, cold, tiredness, grumpiness, and hangovers.
The marathon is the easy part. It’s the constant grind of the training that kills you—and finding ways to keep it fresh and interesting is part of the challenge. Some exercise nuts think they’ve found a way to live their routines up: by using the AI chatbot ChatGPT as a sort of proxy personal trainer.
Its appeal is obvious. ChatGPT answers questions in seconds, saving the need to sift through tons of information, and asking follow-up questions will give you a more detailed and personalized answer. But is ChatGPT really the future of how we work out? Or is it just a confident bullshitter? Read the full story.

How new technologies could clean up air travel
Aviation is a notorious “hard-to-decarbonize” sector. It makes up about 3% of the world’s greenhouse-gas emissions, and airline traffic could more than double from today’s levels by 2050.
When it comes to flying, the technical challenge of cutting emissions is especially steep. Fuels for planes need to be especially light and compact, so planes can make it into the sky and still have room for people or cargo. But the industry has some promising ideas for cleaning up its act—and some of them are already taking off. Read the full story.

The big story
Inside effective altruism, where the far future counts a lot more than the present
October 2022
Since its birth in the late 2000s, effective altruism has aimed to answer the question “How can those with means have the most impact on the world in a quantifiable way?”—and supplied methods for calculating the answer.
It’s no surprise that effective altruisms’ ideas have long faced criticism for reflecting white Western saviorism, alongside an avoidance of structural problems in favor of abstract math. But as believers pour even greater amounts of money into the movement’s increasingly sci-fi ideals, such charges are only intensifying. Read the full story.
