What replaced Jarvis in Iron Man?

After J.A.R.V.I.S. (Just A Rather Very Intelligent System) was destroyed by Ultron in Avengers: Age of Ultron, he was replaced by Friday, another artificial intelligence (AI) created by Tony Stark.

Key Details about the Replacement:

1. Friday:

   • Friday became Tony Stark’s new AI assistant after the events of Age of Ultron.
   • Friday was introduced in Avengers: Age of Ultron, where she took over the role of managing the Iron Man suits and assisting Tony in his technological operations.
   • She had a more dynamic, less formal personality compared to J.A.R.V.I.S. and was voiced by Kerry Condon. While still highly professional, she was slightly more sassy and responsive to Tony's humor.
   • Friday is notably more combat-focused in her functions, assisting Tony in battles and managing various tasks related to his suits and technology.

2. Vision:

   • J.A.R.V.I.S.'s consciousness was not completely erased. Instead, it was uploaded into a new body, which became Vision.
   • In Avengers: Age of Ultron, Vision was created by Tony Stark, Bruce Banner, and Ultron, using J.A.R.V.I.S.'s programming combined with the Mind Stone (one of the six Infinity Stones).
   • Vision is a synthetic, sentient being, very different from J.A.R.V.I.S. as he has emotions, free will, and a physical form. While he was once a manifestation of J.A.R.V.I.S., Vision became his own character with a strong moral compass and role in the Avengers.

Summary:

• Friday replaced J.A.R.V.I.S. as Tony Stark's primary AI assistant, continuing to manage his Iron Man suits and other technological systems.
• J.A.R.V.I.S.'s consciousness was transformed into Vision, a physical, sentient being who plays a significant role in the MCU but is no longer an AI assistant to Tony Stark.

Both Friday and Vision filled the gap left by J.A.R.V.I.S. in different ways, with Friday maintaining a functional role as Tony’s assistant, while Vision evolved into an independent character.
