It looks like you're trying to make a clever joke in the style of mocking SV types for reinventing products that have existed for generations, except you're wrong. The parent means the Amazon delivery locker kiosks they're putting in all kinds of retail stores, where you enter a code to unlock the locker with your package. It is secure from theft, has variable sizes, works 24/7 with no waiting for a clerk, and can fill the delivery needs of a neighborhood far more efficiently than apartment-style mailboxes where each resident is assigned their own small locker.

I wish that USPS would get into this service, because I'm not a fan of Amazon and package theft is rampant. It is nearly impossible to replicate the Amazon locker experience through USPS and other online retailers. If you want to order a package and pick it up at the post office, the best you can hope for is to beg the seller to send it to you via general delivery, which many do not allow. And even though renting a PO box lets you ship packages to the post office and pick them up, most retailers won't ship to PO boxes. A PO box costs about the same per year as a Prime subscription. Plus, you still have to wait in line to pick up your packages.
