None of this is an impossible demand. This is how products work. It is either better than the other alternatives (there are always alternatives) or they are not going to survive. And all the alternatives will always fight back.

Will Signal ever replace WhatsApp ? No matter how much privacy or open source laurels it has .. and enenglised by likes of Jack .. The point is , if a problem is already solved .. why waste time on that when there are millions of other problems to be solved ?
Hundreds of companies tried to replace Google by copying Google .. no one succeeded .. chatGPT rattled it in a matter of months .. why ..because chatGPT didn't copy .. it solved a new problem ..
They need to build a better app if they want to replace what's app.
Now that we are in the world of AI agents - why would we build a better Signal ? .. wouldn't I ask my AI agent to send a message to you or post it on some social ( or socials of my choice) ?
If that is true , user doesn't care if my message is being sent by signal or whatsapp or OxChat .. . This is a huge opportunity for nostr cuz ID is local .. agent doesn't need KYC with Meta ! .. just a LOUD Thinker ..
I mean we still need a pipe ( client) and a protocol .. but from user standpoint , it is simply a new interface ..
And frankly .. I can do without the global feed .. let AI figure out what is most suitable for me and give me notes to read to read in a "discover" tab - just like Perplexity is doing with news .. I know it is still a copy ..but a different take on social paradigm .. the current interface was discovered by Twitter almost 20 years back !
