Less a specific technology and more a mindset. Repairing things around the house. Today, it's almost always rational to throw out the broken thing and buy a new one. There are a bunch of reasons why that's true: cost of one's own labor, lack of discrete replacement parts, lack of repair documentation, improvements in technology since original purchase, risk of further breakage, risk of injury to self, etc.

But the real cost is that people generally don't know how things work anymore. They're just black boxes, even simple things like a coffee maker or a clothes dryer. Which further reduces the demand for repairability, which seems like a downward spiral toward everything being disposable.
