Hmmmm.... So actually it cant replace the messanger that we know nowdays or lets say they are still faster BUT in my understanding it can be really good for example business porpouse because of the security. Or lets say i think it can replace the emails. Becaise until now still most of the companies useing emails but everybody knows that they can hack it easily. So maybe this will be better option.
I am not a pro. in this topic but this is how i understand 😊
I think it is good product and it can be popular in the future. 😉
