Omg <3 Not only is this such an important issue that needs way more attention, but he did an awesome job explaining the true issue and an actual solution. This is lovely - I give him major kudos!

I was fortunate enough to catch this talk in person, and it was awesome and really informative. I still think about it when I see these lights in my neighborhood; from your talk, I learned that these create tremendous energy waste and light pollution. And paradoxically, brighter lamposts don't make places safer at night (someone could stand directly underneath some kinds of lamposts and you'd never see them if there was an overwhelming glare; i remember that pictured example and think about it in creepy parking lots). This kind of light pollution is also really disruptive to both nocturnal wildlife and humans with photosensitivity and/or poor sleep hygiene. So yeah, it's all just wasteful, harmful and unnecessary. City planners and developers should really follow the example set by Albuquerque, New Mexico -- their lighting laws/dark skies are a major win for stargazing tourists, the bats, and the city's residents, who are benefitting from less pollution/waste, cheaper energy bills, better looking night skies, and Albuquerque's thriving tourism economy. Thanks for a genuinely interesting and informative talk, Mr. Carhart; I really, really enjoyed listening to you.

Very nice talk and man. It's great to know he has been thinking and campaigning about this for so many years.

I didn't catch anything about hackers helping solve the problem though, did I miss something?
There are obvious ways of course, motion sensors used intelligently, and others. We have areas in Denmark where the street lights turn on in front of cars, and turn off behind them.

We have turned the island I stay on into a Dark Sky Park (IDA approved), so it's a subject that interests me very much.
