b) There is no question that these taxi/delivery apps have reduced costs. Not to mention his vision for the future of food delivery has hardly been implemented.
Apps are merely being tacked on to existing business models. This isn't the world Steve's getting excited about... it's the first baby steps.
But once businesses are designed from the beginning with apps, decentralized delivery, automation, etc in mind - just as he mentioned his sister in law did with her Vietnamese food service (by just getting a commercial kitchen with no retail front-end besides the app).
Nor has the true power of Uber-style delivery/driving apps been close to being reached yet. There is tons of potential for change still to be done, which will further reduce costs.
c) Yegge himself said this goes beyond food/transport
> Here’s the thing, though: Transport and food are only scratching the surface. Same-day food delivery can be generalized to same-day anything delivery, for instance. We’re going to see major disruptors happening yearly (if not faster) for many years to come. Payments and financial services are up next, and they’re a staggeringly huge opportunity.
