If you dont restrict yourself to only hardware then there is plenty of cool stuff. Im using git repo RSS feeds to inject changelogs directly into my veins and its great tbh. There are cool new open source TTS and STT models releasing, single camera motion tracking is getting really good, etc. You just shouldnt look towards commercial products for this excitement, because those are always just enshittified lock in traps. The real juice is in hardware independent open source software that wont fuck you without consent.
