The RK3576 is a really interesting/versatile chip and it is awesome to see major effort going into baking full support into the linux kernel. I could see it opening up a ton of doors for awesome FOSS hardware projects w/ AI accelerated workloads.
One idea I have (but realistically will probably never build) is an e-ink notepad with a microphone that I can ask to generate custom note-taking templates. As a niche example, I'm imagining I'm at a baseball game and I can tell my tablet "hey give me a baseball scorecard template" only for it to generate one for me. Then if there are a ton of subs or the game goes super long, I can modify the template in place with follow-up commands like "add more rows for player substitutions" or "make it support up to twelve innings".
I imagine having a chip like the RK3576 fully supported in the linux kernel could make building a device like this much much easier.
