This is a great piece of passing the mantle on. I have a feeling when Tony had "Fury" make sure Peter got the Edith glasses, I'm absolutely sure Tony would no longer need to worry about protecting the world, leaving it in Peter's hands. I'm positive Tony knew that after the Time Heist was over, Cap was gonna get that life he was always telling him to get and I think he also knew Cap was gonna pass his shield to Falcon as well. But Tony knew Peter would be his successor much like how Deku is All Might's. He knew how dependable Peter was and probably even trusts him as much as Rhodey and any of his closest friends in the Avengers and even Pepper. I honestly wouldn't be surprised that Tony left some of his Stark Industries resources regarding any tech/projects for Spider-Man seeing how the jet in Far From Home contained a costume designing machine with all the files Tony had for new designs for Spider-Man much like how he did with his armor. And honestly, seeing Peter with that holographic gauntlet reminded me of Tony designing the MK II armor. Tony, you can rest now. Peter will carry on your legacy...after getting through some legal issues. But I think I can speak for everyone and say we love you 3000
