I think this is really a future, this is the product that I really expected to become reality at some point. If we assume agents become even more common in the future, then I don't think we would really have a lot of modern software. Most of it is really is not needed at all.
Most apps that people use are really very similar and don't have anything original. It would make more sense for it to be more personalized. For example someone might prefer not to interact with interface at all, and just access services just by chatting with a bot, while other person might want only last steps to be provided as UI. For example to see summary of his cart before paying. While another person might be insterested in just browsing all options. Some might prefer to have filters, while other would want AI to filter everything for them.
I think the real result would be when all services would be automated by AI. Like if you want to be a small business, you no longer need to build anything. You just describe what real life services can you provide: delivery, barber, baker, cleaning, repair. Then all of that would be in some agent network, and available to other agents as an option. While humans on both sides would just get a bridge between them in whatever form is most comfortable for them. Buyer might get a list of bakeries as normal ecommerce website, while the baker might just be someone who receives phone calls explaining him what his next order is in human voice.
