AppleTV is quite popular, and Vision Pro is unlike anything I've seen from anyone. The existing AR/VR headsets are not smashing successes. People walk out Vision Pro demos quite stunned/shaken from what they've experienced.Sometimes this strategy has worked out well for Apple. Notably the iPod, and iPhone where they added and improved upon the original MP3 player and smartphone.
But lately, it feels like Apple has been simply chasing and just catching up to what's already been done. I'm thinking AppleTV, VisionPro, Maps, and of course Siri.
When ChatGPT, Bard and others are already in the mainstream, I do wonder what's Apple's AI assistant will bring to the table. Hopefully something amazing, but maybe nothing special. And just being on the millions of iPhones and iOS devices is good enough for Apple.
Bard is kinda dumb in my experience, ChatGPT is very cool, but I agree with another poster that "conversational AI" is not the same as "execute a task." Multi-step task execution isn't really the domain of LLMs so much as just improving how requests are handled at intake.
BTW, you can already get Siri to answer via ChatGPT with the Shortcuts app, but ChatGPT cannot turn on the lights or unlock the door because it doesn't understand your specific setup.
