My thoughts exactly.

I'm hoping for it to spread to impoverished countries or slums. If the price of production is indeed low, this could be a great chance for them.

Then let's hope it doesn't get associated too much with homeless people's food, and the rest of the world might adopt it as well. Once a large-scale production industry exists, there might not be such a high threshold for adoption. People are in a hurry to eat so often, if they could just pass by a place to grab some Soylent, they'd certainly take the opportunity.
