I know it is a weird takeaway from that episode, but I found the ubiquitous social media tweaking while at work to be incredibly unprofessional and I wondered how that society could get anything accomplished... ever. And the whitewashed physical world with almost no other real technical improvements emphasized that point for me.
Their scores would also be tied to their jobs, people would get things done because it's another way to advance your rating. I saw the lack of technological improvements as the episode taking place roughly now, the tech for the rating system basically exist already.
Remember the truck driver with a ~1.4 rating? She said she was a ~4.6 when she was young. That made me think that the technology had been around for awhile and that technology had stagnated.
