Låt oss ta reda på detaljerna i detta.
To create Vision, Tony didn't just push JARVIS code into an artificial body. Tony also mentions that he "Reconfigured JARVIS' matrix to be compatible with the body". Meaning, He had modified JARVIS.
Most important thing to note is, JARVIS was an AI. Vision is an entire consciousness. He realises this. He is self-aware. That is why he says he no longer JARVIS. He has become much bigger. He transcends from an AI to a full consciousness, thanks to the power of the Mind Stone.
Med hänsyn till dessa två punkter kan vi säkert säga det när Vision sa att
He was no longer JARVIS.
Han menade faktiskt ovanstående. Det betyder definitivt att han överlevde, men har just utvecklats.
But to accomplish this, Tony has modified JARVIS, meaning we might never see JARVIS running Tony's suits, or Avengers HQ or his quinjets. The prospect of "Friday" is interesting though.
