Some form of Dash exist with industrial manufacturing and assembly( some part call it bins) Where the no of items are limited ,where obviously it scales nicely. To think that the Dash is a solution for all the items is not productive. I think Dash may have market for consumer items like diapers,sodas, Ramens kind of stuff, basically which once you consume more frequently.

Writing it off might be premature, at least it is worth a try.
