I read an article in the New York Times about Elon Musk wanting to make X, formally known as Twitter, into an everything app. The article also mentions other attempts. Would that be the last thing we would want?

I can see why Elon would want it: total domination of the app market and massive profits. While a user might find it convenient, it would be a total lock in to one app that would make it difficult to move to other apps. If the app went under, a likelihood for X under Elon's control, the user becomes completely disconnected. The app would also be the dream target of hackers trying to steal all you data.

It's not that hard to use multiple apps. I'm sure most of us have dozens of them. I have high security on my financial apps and not so much on my social apps. I don't want to do two step verification to get back into kbin every time I get logged out. Specialize apps for specific purposes makes a lot more sense to me.
