Can't say until I actually here something about it. It could be rubbish, it could be amazing. It could be secure, it could be unsecure. I'm going to wait to hear what Sony say about it.
However there is the potential for it to be amazing. Imagine playing a game and you get a notification saying '[friend] is starting a multiplayer game of X, Y, Z' and then simply saying something like "Aloy, join game" (I'm thinking they'll go the feminine name route!) and you automatically drop straight into their party in-game within 10 seconds. You could even do something as simple as say "Aloy, find me a game of Duos in Apex/Warzone" and it'll do all the work to get you straight into the game or "Aloy, send the last ten seconds of this game to [friend]" and it'll send them a clip of some feat you've done or trophy you've earned.
To me there's a lot of potential so I'm not going to commit to anything until I see what it can do.
