Let's say I want to replace the forklift operator at my local lumberyard with a robot forklift that can ostensibly outperform a human employee. Even if there is some magical AI program which could theoretically drive the forklift around, identify boards by their dimensions, species, dryness, location, etc., there's a whole bunch of sensory problems that a human body solves easily that are super hard to solve in the environment of a lumber yard. There's dust, rain, snow, mud--so if you're relying on cameras how will you keep them clean? You can't visually determine how dry a board is, you have to put a moisture meter on it and read the result. My point is, even if you have a "brain" capable of driving the forklift you still have a massively complex robotics problem to solve in order to automate just the forklift. And we haven't even begun to replace the other things the operator does in addition to driving the forklift. He can climb out of the forklift and adjust the forks, move boards by hand, affect repairs on equipment, communicate with other equipment operators, customers, etc.

Good luck replacing him in a cost-effective manner.

So what am I supposed to use it for?
