End-of-life dates
The bricks my house is made of are now 119 years old.  They haven't received any updates or substantial maintenance.  The guy who made them is dead.  His company is gone.Yet they are still functional and secure.  They still work with the latest screws.  If I had to switch out my bricks every 5 years, I don't think I'd have any time or money left for the rest of life.Can we make software that's a little more like my bricks?
