I disagree. Basic etc still required effort.

In my opinion, an OS that hosts a local agent can produce things for you on the fly in response to a particular task in addition to the baseline set of features.

Too often have I ran into "you can't do that" in operating systems, especially Macos where you either have to buy a paid app to implement what they should have already, or what you want is niche enough that you have to build it yourself.

Plus and agent can operate across your hardware including the cloud. I could ask something like "graphics cards are expensive and always out of stock so when some pop up can you notify me and show me the price etc" and then receive a rich alert on whatever device I happen to be using at the time it happens, once agents are aware of where we are and what we're doing (yes, it will be pretty dystopian with current governments and the drooling animals who vote for tribalism).

Or being able to be like "I want my photo gallery to show animated thumbnails when I've taken a series of photos of the same subject. Oh, little bit slower like one every second thanks" boom done.

And much UI will becomes defunct in the first place, UI only exists because of many annoying discrete steps we have to do to get something done. If I can just ask an agent to do the thing I want then I don't care about that.

It's like how I only need to make a PowerPoint now and then and every time I open it I've completely forgotten where all of the stupid fucking buttons are in the stupid fucking ribbon bullshit they made.
