The future of Nostr clients is multi-continent, multinational, multilingual, multi regional and multigenerational. It will not just replace Twitter but Instagram, FB, TikTok, Pinterest, Snapchat, etc 
It won’t need you to be literate in any text or written languages. 
To build this future there will be amazing client experiences. 
Clients: Companies and developers could create custom Nostr clients tailored to specific needs and user experiences, from lightweight messaging apps to full-featured social media platforms encompassing all types of media.
Interoperability: Despite the variety in client applications, all would adhere to the Nostr protocol and agreed-upon NIPs to ensure interoperability. Users on different clients could interact seamlessly, sharing and receiving media without barriers.
However none of this will matter because like 99% of the Internet do not know what SMTP or SMPP is the future clients will never know what Nostr  or relays are. They will be buried somewhere deep  in the “settings” 😀
