I've done cursory research on this person, and my understanding is that she claims she will still be teaching science but only wearing sexy tops on. I don't know how truthful that is but even some Olympic athletes said they are in Only fans but "only being sexy without showing", in order to supplement their income. I don't really fault people for this considering the worsening cost of living crisis.
Sex work is real work. When we sufficiently progress as a species the concept itself will become incomprehensible because survival sex will become incomprehensible.
