“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.” “Which means that Copenhagen, a city of 1.2 million people, saves $357 million/yr on health costs because something like 80% of its population commutes by bike.” Investing in bike infrastructure saves money.

One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss
Copenhagen, the bicycle-friendliest place on the planet, publishes a biannual Bicycle Account, and buried in its pages is a rather astonishing fact.

over the past few weeks several AI evaluation/cybersecurity experts have explained how what's happening is a result of human incompetence rather than "AI going rogue". I'm begging the media to show a shred of journalistic integrity and stop parroting what altman or amodei say

I also find it ironic billionaires chasing longevity while overlooking something as basic as clean air, despite evidence that multiple pathogens accelerate dementia and other neurodegenerative processes. Living longer is great. But what’s the point if your brain doesn’t come along for the ride?

2. I'll probably keep assigning homework but stop grading it (just offer problems as suggested learning opportunities), stop giving take-home exams, and have to revamp how I advise and grade semester projects. I'll probably shift all assessment to in-person exams, written or oral.

One data centre proposed for Toronto would use over 50MW of electricity. That’s as much energy as 50,000 homes or every home in East York. Too many data centres could lead to unsustainable emissions, water use, and electricity prices. We need a pause on new approvals to set some ground rules.
