In my time behind the bar, I have met some incredible journalists. Folks I trust implicitly. @jsidman is one such reporter. And a guild member! I must say however, I’m disappointed to see her not mention the pug in all her otherwise spot on Michelin reporting.

"Pittsburgh is undoubtedly the cockeyedest city in the United States. Physically, it is absolutely irrational. It must have been laid out by a mountain goat." -- Ernie Pyle in 1907 about our street grid.

The accuracy!

The US has a rich history of rail travel. While American passenger rail may be falling behind other countries when it comes to passengers and daily departures, its beautiful stations are no slouch.

Here are 10 of America's most beautiful Amtrak stations...

This paper shows the effect of having $10k in student debt (vs. no debt) on startups. Debt:
💸Lowers the chance of launching a startup by 7%
💸Drops startup revenue by 42%
💸Hits tech & fast-growing startups hardest
💸Makes impact of startup failure worse https://t.co/WEYHGlJYol

An unexpected benefit of electric cars is less car crashes

This paper expands on research showing how bad pollution is for thinking: an increased PM2.5 pollution leads directly to more car crashes. A one unit increase in PM2.5 increases fatalities by 1%! https://t.co/gJaw5SgsKu

Air pollution is terrible for your ability to think.

Using a case where only some schools had air filters installed, this paper shows that cleaner air increased test performance by 20% of an SD - the same impact as smaller class sizes or intense tutoring! https://t.co/woETxx54t9

Air quality alerts have been sent in 17 states and in cities including Baltimore, Boston, and Minneapolis

I think it is important that everyone realize that, within months, how people relate to writing is going to change, for better & for worse.

I have been playing with Google Docs with built-in AI & it is clear that most people will start much of their writing work with an AI draft

[Ethan Mollick @emollick]

I got beta access to the version of Google Docs with AI built-in.

It is clear that tons of work that could be meaningful when carefully done by humans are now going to be done mostly by AI, with huge implications for how we think about work tasks.

Think performance reviews, etc

@JohanSalomon @ChekriK ?

What requiring AI has let me do with my syllabus:

Old assignment: outline your business idea.

New assignment: outline your business idea, make sure your class goals are “ambitious to the point of impossible.” Simulate three famous founders to criticize it. Give 10 weak points.
