If cheap enough, it may solve a problem for people who don't know that they need to hire engineers to make that conveyor belt, or if they don't know if the conveyor belt will be needed for more than a few months.

If it's general enough, but does simple tasks, that's still a win over 'this is a nutcracker that work only with this precise nut +-1 mm at a rate of _exactly_ 1 nut per hour +-0.1 seconds.' which may be some of the types of machines out there.
