Interesting, you don't think of Krispy Kreme as making robot donuts. Curious that Macdonald's, with so much careful specification of all processes, hasn't done this, at all. e.g. fry/remove/salt fries. (though their standard coffee is mostly automated). Macdonald's is so well-placed, I can only assume it isn't actually cost-effective for them. Maybe it's worth it for Momentum, for the PR? Or, by starting from scratch…
But maybe the simplest explanation is that big businesses are not very much optimized for innovation, so it took a startup.
