It may be a ways down the road. But ride-sharing type businesses will put a dent in volume for all the delivery companies. The possibilities are interesting.
There is opportunity, but the author doesn't have a good grasp of e-commerce companies or shipping companies.
His examples revolve around people picking up things for other people while they are out conducting their own affairs. Picking up fresh-baked cupcakes at the neighborhood bakery for immediate delivery, for example. That's not something we do, nor is it something we
would do. Further, that's something that's a product that e-commerce companies aren't going to try very hard to tackle. Fresh-baked goods, overnight?
The biggest problem that they guy is missing is that e-commerce is alive because of price. People aren't going to pay full retail AND a delivery fee when they could either go pick it up themselves or get it via Amazon for a much better price.
There is a niche to be filled with this if you need something the same day, it's nearby, and you can't or don't want to go get it yourself and are wiling to pay extra.
