With time and training I suspect Peter could learn the iron Man tech
Also, Far from home makes me wonder what other security protocols tony has in place in case of his demise?
If anyone ever steals and learns to replicate the iron Man tech, especially the mini arc reactor then an armor wars shall occur.
I recently read that Sony is ready to deal again if MCU involve Venom, ...could help boost the box office take for Venom 2 (I thought with actor Woody Harrelson involved in it would bring interest in that project).
Like that Marvel offer to Fox decades ago, they'll give them Daredevil and help them make good Xmen movies for the use of Galactus and Silver Surfer, ...Marvel/Disney can give Sony Miles Morale's Spider man and Prowler, ...and let the MCU make a 3rd Spidey movie and the use of Norman Osborn.
Maybe the deal with Sony sounds bad, but this allowed Marvel to do movies like Antman, Guardians of the Galaxy, ...and upcoming Shang-Chi, Eternals movies. I don't think they wouldn't tried a Guardian movie if they were busy with X and Spidey movies.
