There's also a reason it's called a singularity, it sucks everything in that touches it but otherwise has very little influence on anything else.
It'd just be waisting compute money with no obvious way of recouping the cost. Doubt many people would be interested in paying for Siri.
But people in general don't seem to be interested in voice assistants in general. They were a huge hype when you basically had to manually uncheck boxes to not accidentially order an Amazon Echo, etc, but as quick as the hype was there it was gone. To my knowledge Amazon has yet to make any kind of substantial revenue with Alexa stuff.
With LLMs I would expect this to be even more of an issue given how costly the inferencing alone is when we're talking about an LLM. And yes, the utility will likely increase substantially with the adoption of LLMs as opposed to previous language processing techniques, but I don't think this will outweigh the disinterest in the overall technology.
When voice synthesis, long context etc. i'm pretty sure a lot of people would love to have a private "Her" like friend/assistant that could both be therapy, a PA and a friend, and i don't think we're that far from that. Dystopian and lonely as it is.
When they achieve something like 99.9999% accuracy and near-undetectable latency, I will become much more interested in them.
As it stands now, if I have to repeat something -- ever -- I'd rather just type it.
Apple's key strength is Integration. If their AI play is different and better, this is why it will be so. When Samsung puts AI in their phones, its a sparkles-and-magic button in an action bar that pops up a list of actions that might as well be chat prompts. Microsoft releases 365 Copilot and its a chat sidebar to the normal Office apps. There's real opportunity to integrate AI more deeply into the OS and the actions users take when using the OS.
I don't know what form that takes; that's Apple's job to figure out. I think WWDC this year is when we'll be presented their vision (ha) on how it fits together. I think: If it looks a lot like the Galaxy AI event, then your take is right and I immediately become bearish on AI and honestly bearish on Apple's future among the ultra-high-value companies of the US. But, I'm leaning toward feeling that they're going to surprise us, and I'd put money on the outcome that WWDC represents an "iPhone Moment" for AI, leaving a lot of organizations scrambling to understand how their product fits into Apple's world and not the other way around. But, we'll see.
AI is a tool. Are houses worthless because any hammer can create them?
Put simply, have you heard of or do you follow any AI based creators? I can name 10 or 20 artists, content creators, movie directors, or writers that I respect pretty much instantly. Can't really do the same thing for people using AI.
