Yes of course there's only one way to have a succefull life and one should just follow what others before them have already done, in order to be successful, who needs to think for themselves and make choices, just read the financial papers make a lot of money and then when you are dead and forgotten by the world at least you will have all your money to comfort you in the afterlife
So basically you say the future of web would be everyone gets their own Jarvis, and like Tony you just tell Jarvis what you want and it does it for you, theres no need for a preexisting software or to even write a new one, it just does what's needed to fulfill the given request and give you the results you want. This sounds nice but wouldn't it get repetitive and computationally expensive, life imagine instead of Google maps, everyone just asks the AI directly for the things people typically use Google maps for like directions and location reviews etc. A centralized application like maps can be more efficient as it's optimized for commonly needed work and it can be further improved from all the data gathered from users who interact with this app, on the other hand if AI was allowed to do it's own thing, it could keep reinventing the wheel solving the same tasks again and again without the benefit of building on top of prior work, while not getting the improvements that it would get from the network effect of a large number of users interacting with the same app.
