Its a control thing. The online safety act connects every account to a government ID, leading to easier arrests if you say somehing the good ol' government dont like. Its an attack on free speech
I think we are in the timeline where AI tales over. Look at Elon's tesla robots. I don't think AI will become sentient and rule/kill humans, more like corrupt rulers using AI to generate videos of people they don't like commiting a crime, and using it as proof the victim did the crime.
last time i used twitter it still had a bird icon. it was like a month after Elon bought it i left (online chillout, i never made another account, might soon idk) so things might be different
