A human who liked caring for horses, feeding them, brushing them, comforting them during thunderstorms, blanketing them in cold weather, riding them through the fields, tolerated mucking out the stables, is not just biding their time until someone invents the city bus so they can free up all of that timewasting labour and sit in a box turning a wheel left and right for the rest of their days, and then the self-driving taxi, so they can finally "be free". You can say that they can still care for horses today, but if mansions don't need stables and horses, if deliveries don't use horses, then it's no longer a tangled up job, life, part of a community, way of earning money, way to get some respect, feel useful, it's just standing in a field stroking an animal.
