The way your writing never fails to resonate with me is just so good. I definitely am going to go listen to your recommended songs. The way that "This Year" got me through undergrad cannot be understated either.

Don’t let mega-constellation-building billionaires steal your night sky Satellites are wonders of modern technology that have improved all of our lives. But having more than a million of them in orbit could destroy our view of the heavens and seriously damage our planet

Elon Musk has already started plans to launch a million satellites.

Yes. A MILLION.

This is a colossally bad idea, and it's not too late to make your voice heard. I explain everything:

recently my friend's comics professor told her that it's acceptable to use gen AI for script-writing but not for art, since a machine can't generate meaningful artistic work. meanwhile, my sister's screenwriting professor said that they can use gen AI for concept art and visualization, but that it won't be able to generate a script that's any good. and at my job, it seems like each department says that AI can be useful in every field except the one that they know best.

It's only ever the jobs we're unfamiliar with that we assume can be replaced with automation. The more attuned we are with certain processes, crafts, and occupations, the more we realize that gen AI will never be able to provide a suitable replacement. The case for its existence relies on our ignorance of the work and skill required to do everything we don't.

Trans kids are under attack. Every year, I make a thread of trans and nonbinary girl scouts you can get your cookies from.

Lets get our cookies from them this year in solidarity!

I definitely second the Percy Jackson books. I also loved the Nancy Drew and Princess Diaries books. I remember friends in middle school school liked the maze runner series as well.
