Yeah well, be careful around Tony when you're mentioning stuff like this. He's here, but the battle of New York really messed with his head, we had another global crisis because he lost his mind and tried to make an advanced AI system to protect Earth and it ended up turning on us. The battle of New York was hard on all of us, but he's the one who made the one way trip to end it. The fact that he's still around is pure luck, and he knows it. He isn't the same after that happened, so just... tread carefully.
Well I know that Vision has one. I'm not sure if you know who he is, he's a.. person? Creature? That Tony and Bruce literally made, they downloaded one of his AI's into it's brain and the mind stone gave him it's power. He's good, though. Worthy. As long as he has it, it won't be joined with the others. I'll keep it in mind though, in case I ever get back home.
I have a feeling that you're just from a point in the future that I haven't gotten to yet. Which sounds swell.
