There will be a huge fight over whether copyright vests in works generated by a few humans using AI tools. That will determine whether it is economically viable for large creative industries to replace lots of human creators while still being able to window and monetize the content the AI spits out.

It was hard for me to be chatting since we had a few folks watching from bsides, and the chat window was very small. I'm glad to be able to see it now.

The judges in WV have seen enough.
They say that if the ICE continues detaining people in ways they have unanimously deemed illegal they will start issuing civil fines and contempt findings β including against state officials who help them carry it out.

No public school, school district, or public employee acting
in an official capacity shall engage in the pedagogy, praxis,
or inculcation of critical theories or related practices that
promote division, dialectical world-views, critical
consciousness, or anti-constitutional indoctrination.
Sorry I missed this the other day. New Hampshire Republicans are literally banning the teaching of dialectical thought. What a world.
(Bill passed House, now goes to Senate with GOP majority, and then to GOP governor.)

It's never a good sign when someone needs to declare someone else's "real name," that they can define for you.
In a free society, you can call yourself whatever you want, introduce yourself that way, & expect polite people to call you that.
You don't remember Bob Dylan's other name β¦ & who cares?

This is incredibly blunt antisemitism, obviously, but it's worth pointing out that the core of itβthat Jews are not "true" Jews or are perhaps even fakeβis maybe second most common antisemitic belief in America and has been rapidly spreading across the left for quite a while.
