I’d say stage 4 is being the keystone attendee: if you don’t go, the whole thing falls apart. Even if you somehow manage to get out of the meeting, it has to get rescheduled because it “needs” your input. The meeting thus becomes inescapable.
Stage 5 is when everyone else realizes you’re in stage 4 and begins to cater to your availability and preferences. Obviously this is mostly theoretical.
The warriors of the resistance to the AI-pocalypse will wear red sneakers and wisecrack like it’s 1994.
