Keeping this in view, why did Tony Stark replace Jarvis with Friday?
FRIDAY is a replacement for J.A.R.V.I.S. due to JARVIS' matrix being integrated with the Vibranium infused artificial body also known as The Vision.
Beside above, what happened to Jarvis? What happened to Jarvis at the end of Avengers: Age of Ultron. Towards the end of Avengers: Age of Ultron JARVIS uploads himself into a lifeless Virbranium android. This process creates Vision. Then before the final battle we see Tony Stark uploading a program called FRIDAY into his suit.
Also asked, why did Iron Man name Jarvis?
Jarvis (Edwin Jarvis): It is Artificial Intelligent Software. Stark operates its computer by talking to him. The name Jarvis came from the iron man comic in which Edwin Jarvis was his servant and used to do all of the work of his home.
Is Tony Stark the new Jarvis?
Another possibility that has been floated is that Downey could provide the new voice for Spider-Man's Stark-designed suit. In other words, that would make Tony the new Jarvis. That was the disembodied voice who was Tony's AI assistant played by Paul Bettany, who went on to play Vision.
