Code is inventory, not debt. Inventory is good and bad. If someone comes to your store and everything is out of stock, you will make $0. So you want some inventory. But if you have too much inventory and nobody is buying anything, then your inventory just rusts in storage and becomes worthless. Code is pretty much exactly the same. Most features are sitting in storage in the hopes that someone comes by to buy it. Sometimes they do! Sometimes they don't. If you were the guy with a toilet paper warehouse in March 2020 you did great.
