One thing that I heard from Steve of the Dead that I thought was interesting is that Phil is losing all capacity to make friends or connect to other people in any way because he doesn't do anything.
He is like an old person that says his best days are behind him and is just waiting to die, you know how some old people don't really do anything but watch TV or listen to the radio? If you ever interacted with a person like that you know there is no way of having a conversation with them because they don't do anything, the only thing you can talk about is of the soap opera they are watching. with Phil is the same thing.
Phil is not informed about any current events or anything related to the real world so you can't have a conversation about the society we live in or anything like that, he doesn't have any hobbies so he can't talk to people about his hobbies or connect to someone of similar interests, there is no ice breaker with Phil because he is a literal blob that just exists to consume door dash and mobile games, when you make a friend the conversation starts because the two of you have something in common to talk about, then the more you talk about the less you talk about that topic your two were initially interested in and you move on to other topics, Phil is incapable of doing that because the only things he is interested in is consuming pig slop, WWE candy crush and being a victim of detractors, even if he tried to talk about gaming (something he uses as his whole identity) the other person would think he is a fucking retard(because he is) since his opinion are misinformed and dented, if he starts a conversation with someone about gaming the other person will think he is a dent and will stop talking to him the moment Phil says Bugsnax is game of the year or that street fighter super turbo is the pinnacle of fighting games.
On top of having an absolutely terrible personality, low IQ and some autism you can't talk to him about anything because he just exists.
