I feel that the director just wants to show the multi-faceted Steve Jobs, showing the cunning of Steve Jobs through the $350 thing, and showing that Steve Jobs is not a casual success through more than 100 phone calls. Through his attitude towards Lisa, he shows that he is a bit of an asshole, and he has his own life experience. The influence of his character, in many respects, is a biography after all. It can only show the multi-faceted character of Jobs through a lot of small things. The director wants to explain that he is not a god, but a person who is somewhat shady but pursues the ultimate perfection.
When he said that he wanted to replace Jill, he really grew up. Maybe at that time he would understand the helplessness of Sculley to replace himself at that time, because to change, it is necessary to clear the obstacles.
