We need some sorta conveyor belt to move stuff then, having to manually move it via cart or w/e is such a pita. Minimally we should get transport contracts for the job board and make a noob do it or something.
Conveyor belts for small-range transportation in factory buildings is something we consider for the bit of automation we want to do, but aside from other games, the focus in Eco will never be in automation and instead will ever also focus on good old manual work.
For the mines we expect players to use the elevators. Transporting stuff via trucks and the elevator of course is not as convenient as just teleporting it to the top, but it's the intended way.
