Here’s the truth about the ‘planned obsolescence’ of tech

“They don’t make ’em like they used to,” as the idiom goes. So it would seem for the Centennial Light. An astonishing, record-setting 115 years after someone first flipped it on, this light bulb is still faintly shining in a fire station in Livermore, California. (You can see it for yourself on a webcam that refreshes every 30 seconds.)For the multiple generations of us who have since swapped out more burned-out light bulbs than we can remember, the Centennial Bulb’s longevity must seem like a slap in the face. Surely, if an incandescent bulb made with 19th Century technology can last so long, why not new-fangled, 20th and even 21st Century bulbs?
