I told myself I was going to replace them with LEDs once they break. The problem is that they never do. The ones in my grandparent's house are around 40 years old and I think only one went out in all those years.

    It completely ignores the reason for the 1000 hour decision. You could always make bulbs that last forever. You just had to make the filament thicker. As it thickens, the efficiency drops, and by a lot.

    1000 hours was decided as an even balance between longevity and efficiency. Some utility companies would even give away 1000 hour bulbs just to keep people from connecting 2500 hour bulbs, which would've used a bunch more power.
