Two empty skycrapers
Only one employee left inside
It's 2030, every job has been automated. Facilities issues are handled by robots. Desks are empty. Nobody from security staff to janitors to executives are left. All of the doors are locked. The lights are on. A.I. took over all parts of business function or the jobs have been outsourced, but those went away as well. The company is still around, profits and stock are trading really high, but none of the staff are needed any more, executives don't need to hold meetings for anyone, all but one person is left.
That person is me and I'm not sure how they overlooked me, I don't do anything, but I'm still getting paid.
