In the comics Simon William's recorded "brain patterns" were an integral part of the Vision's construction, why the Vision was seen as a real person and why the Scarlet which was capable of putting all her love into a kitchen appliance capable of turning that love.
After a botched attempt at world domination, the Vision was having a bad week, the the governments of the world got together and pulled him apart into a million pieces and boiled his hard drives, murdering his "sweet and nerdy" personality.
Grief stricken Wanda was given the empty remains of her husband, put back together again like legos, but without a recognizable soul, so she went back to the source, and BEGGED Wonderman for another "copy" of his brainwaves, to which Mr Wonderful had this yo say...
"Whoa baby! Don't you think the reason that tin man, your husband loves you with all his heart, is because I love you with all my heart? Why settle for a shitty plastic impersonation of the real thing, when I'm right here baby, I love you, I want you, and I'm ready to commit to you here and now for ever because we're like destiny, y'now? let's get down!"
"My husband is dead you absolute a-hole! He isn't even cold. For last time i don't want to be with you! I don't have time for this shit! Give me your damn brain patterns, or go to hell and die, you die, go to hell and die, you selfish piece of shit!"
