One a scale of 1–10… how much do you enjoy the smell of your own farts?
Even in a world where you’re not putting the bodega out of business and you have the best intentions, what you’re talking about is an artisanal vending machine. Give yourself a “let that sink in” moment, perhaps use the “just because I can, doesn’t mean I should” wisdom, table the idea, and move forward with your life. The planet is slowing dying because over consumption and you’re building a product that will add to that consumption. How ethical can this idea really be? Stop bullshitting yourself and build something humanity actually needs.
I don’t know you, but I want to believe you’re better than this, Paul. You clearly have access to resources and people many of us do not have. Solve the planet’s problems…but not with fancy vending machines.
