i've had dynamic lock screens available since my 2010 HTC desire... don't really see how that's new. absolutely ruined the battery life so i never really used it but it has definitely been an option on every phone since.
as for llms in phones, i will do everything i can to keep them out. if the npu chips were open and had published apis it would be a different thing. as it stands now it's just a black box data vacuum that can tell jokes.
