Why would you put yourself into an obvious dead end street? People already have problems leaving whatsapp for better messengers. People have a hard time quitting their amazon-addiction, even though there are many alternatives out there. Imagine you put all your eggs in one basket (messenger, shopping, payment, etc.) and lock down everything in one app. This might work for autocratic regimes, that push this idea of an app, as it makes it easier to control everything, but in the western world we like to be individualistic people who like to choose for themself, stand our or diverge from traditions.

Currently in the west, there are multiple shops you can go to. If you happen to have a bad experience (product not at all like the picture, quality, etc.) you can give the app and the shop a bad review and never come back and try one of the others apps. If you have a bad experience inside a Everything App, where also is your communication with friends and the payment... how do you punish the app? No go to the shopping Tab anymore? Review a bad Tab on the appstore? If you leave all the tasks (shopping, communication, payment, etc.) separated in different Apps, you as a user keep more control. You can switch payments without affecting your communication. Imagine getting banned from paypal, whatsapp and amazon at the same time, because the TOS of this everything app. If you are not living in a autocratic state, you can choose (and should choose) and vote with your experience on what service is good and what service needs to go. If you live in an autocratic state, you might possibly can not choose from too much options, as your autocratic regime is trying to push this single apps, that they can control, into every sphere of your life. And if you do use something else, the autocratic state will find ways to make this a reason to have a closer look at you. Don't stand out. Do not diverge from the rest of the citizens. Or else you get the treatment. - I see how Elmo wants this tool on his belt.

The Everything App stand diametrical against the individualistic person belief and an open market. If it were such a great thing, people would have done it successfully in the last 15 years of App development in the West. But there is none of these Apps. Because it is not fitting in a democratic state where services are federated across the market and not vertically implemented in a single app. Its why we have homescreens where multiple apps can coexist next to each other. Is the best homescreen, a single page, with a single app, where when you go inside, then only the variety of possibilities opens up (calendar, calculator, messenger, shopping, etc.) or is this variety of possibilities not already happening exactly there: On the homescreen, in seperated apps.

He can try. But he will fail. Like he failed twitter.
