Lately Apple has done stupid things, but I hope that could be awesome for summon the “new great AI Siri”. Unfortunately I don’t know if Apple will be into generative AI in the short term…I still think Apple have plans for the Action Button to become the preferred method of activating some new iOS/Siri/AR feature. I don't think they added it just to be a programmable button and that's it. The programmable stuff is a precursor to something a lot more bold.
Meanwhile, it could be great to use the action button to activate ChatGPT “conversation mode”
