A 126,000-year-old butt-drag just made fossil history.
A tiny rock hyrax scooted across the sand of ancient South Africa, and that moment was preserved in stone.
Even the smallest acts can echo through time.

To be clear, they will 'make the proof' that Tylenol causes autism by controlling who does the studies and who reports the results.
They have built a mechanism to 'make the proof' for whatever they want so say. About protestors, about elections, about immigrants.
We have to keep speaking truth.

None of us should feel exempt or invulnerable, because if they can do this to our neighbors, they can come for us, too. That said, those of us who are not presently among those being targeted should not focus on our own fear and vulnerability. We should support those in the immediate path of harm.

Please read this absolutely splendid piece of writing that had me cheering, a little bit weepy, and writing in the margins:
"An extraordinary amount of money is spent by the AI industry to ensure that acquiescence is the only plausible response. But marketing is not destiny."

Becoming increasingly clear we’re gonna have to build a parallel infrastructure for all the media we really love. The reason all of this is happening under the color of law is hyperconsolidation, dissent being traded straight up for merger approval, or fear of harassment.
