There are two perspectives on this. What you said is definitely a good one if you're a business planning to add AI to whatever you're selling. But personally, as a user, I want the opposite to happen - I want AI to be the product that takes all the current products and turns them into tools it can use.
I agree, I want a more intelligent voice assistant similar to Siri as a product, and all my apps to be add-ons the voice assistant could integrate with.
