Not everyone can be blogger (even if they wanted to: which they don't). We need to continue lowering the bar of development and value generation so everyone on the network can participate in one way or another.
We need some apps that would be used by masses - like a product review app, like a bill saving app, like a apartment/home service app etc etc.
With the apps data storage and privacy are the matter of concerns these days. One single breach of our personal information can stay alive on the blockchain forever. So I think apps are not the solution for this.
Well, apart from your phone number nothing else is needed. And our phone number has already made out to hundreds of marketing lists - getting calls from anonymous numbers is not avoidable at all - the DND project was a farce. Imagine, only one app would be developed that would be given to retailers and they publish every warranty on blockchain searchable by your phone number.
Yes you're absolutely right. Can blockchain alongwith AI solve this problem?
May be, someone has to build the app.
