There was a discussion on LinkedIn yesterday about the good days of Academic Twitter before everything went to crap and we left. I'm curious why we haven't been able to recreate that here. A lot of the same folks are here, but there's not as much engagement. What's Bluesky missing? ⚛️🧪

So are you saying we SHOULDN’T have raided that battery plant, put the South Koreans in leg irons and frog marched them off to a dank prison for about a week, @katiephang.bsky.social
But how else can we protect ‘Murica and stop all those criminal engineers from tearing us down by building factories

Phang: The South Koreans are here to help build, to help train, to help get this thing up and running so 8,500 Americans can have jobs. But no — the Trump administration, the dumbasses with their heads so far up their asses when it comes to immigration, are just sitting there rounding people up…

What happened to Charlie Kirk is also what happened to 20 children (ages 6 and 7) at the Sandy Hook Elementary School.
I don’t remember the right being this upset back then—do you? 🤨

In a marathon hearing on Thursday before the Senate Finance Committee, RFK Jr. faced a barrage of questions from senators who were outraged by his recent actions.

not just that he has no constitutional authority, there isn't even any particular legal or institutional mechanism by which the president can make anyone treat this as anything other than a weird advisory opinion.
This “explicit” is a weird editorial choice. The constitution gives the president no power over this at all. It’s not ambiguous.
