Obsolete Thinking

“Obsolete” means something has been replaced by something newer that does the same job better—more efficiently, cheaply, conveniently, safely, or at a larger scale. When a thing becomes obsolete, it doesn’t always disappear overnight. You can still find the older version in museums, rural areas, niche hobbies, legacy industries, or among people who simply prefer it. But culturally and economically, the “center of gravity” shifts to the newer solution, and the old one becomes unnecessary for most people.

Obsolescence is not just about technology. It’s about efficiency and fit. A tool, method, or habit becomes obsolete when a better system makes the old approach less useful. Sometimes the “new thing” is a device (cell phones replacing phone booths). Sometimes it’s a service (streaming replacing video rentals). Sometimes it’s a social advancement: a new way of thinking that makes old behavior less necessary.

That’s why people sometimes say “war is obsolete.” The idea isn’t that conflict has vanished, but that war is an outdated method for solving human problems. The more capable we become at building strong relationships—across families, communities, businesses, and nations—the less we need violence as a problem-solving tool. Relationship builds trust, communication, empathy, trade, interdependence, and shared identity. Those forces don’t guarantee peace, but they reduce the “need” for war by offering better ways to resolve disputes and pursue security. In that sense, relationship is the “new technology” that can make war increasingly obsolete: it doesn’t erase human differences, it replaces destructive methods with constructive ones.

Below are 20 examples of obsolete (or largely obsolete) things, paired with what made them obsolete—plus a brief note on why.

1) Phone booths → Cell phones
Cell phones made public payphones unnecessary by putting calling capability in your pocket.

2) Horse-and-buggy → Automobiles
Cars travel faster, farther, with less daily maintenance and greater carrying capacity.

3) Ice boxes → Refrigerators/freezers
Mechanical refrigeration keeps food safely cold without the daily logistics of buying and storing ice.

4) Film cameras (for most people) → Smartphone cameras/digital cameras
Digital photos are instant, inexpensive per shot, easy to edit, and effortless to share.

5) VHS tapes → Streaming video
Streaming eliminates physical storage, rewinding, tape wear, and limited selection.

6) Video rental stores → On-demand streaming libraries
Convenience, selection, and instant access replaced the need to drive to a store.

7) CDs (mass-market) → Music streaming
Streaming offers vast catalogs without purchasing and storing individual discs.

8) Cassette tapes → Digital audio/streaming
Digital audio is more durable, searchable, and doesn’t degrade with repeated use.

9) Paper maps (for everyday navigation) → GPS navigation apps
GPS updates in real time, reroutes automatically, and can account for traffic and road closures.

10) Encyclopedias in print → Online knowledge databases/search engines
Online sources update faster, link to primary sources, and are searchable in seconds.

11) Fax machines (in many settings) → Email + e-signatures + secure portals
Digital documents are faster, clearer, easier to store, and easier to audit and retrieve.

12) Carbon paper duplicates → Photocopiers/scanners/digital copies
Modern duplication is cleaner, more accurate, and integrates with digital workflows.

13) Typewriters (most offices) → Computers with word processing
Editing, saving, copying, and formatting became dramatically easier and faster.

14) Wired-only home phones → Mobile phones/VoIP
Mobility and cheaper internet-based calling reduced the need for a dedicated landline.

15) Dial-up internet → Broadband/fiber/mobile data
Always-on high-speed connections support modern media, work, and cloud services.

16) CRT televisions → Flat-panel LED/OLED displays
Flatscreens use less space and power, offer higher resolution, and are easier to mount and move.

17) Incandescent light bulbs (in many countries) → LEDs
LEDs last far longer and use far less electricity for the same brightness.

18) Physical airline tickets → Digital tickets/boarding passes
Digital passes reduce printing, speed up check-in, and are harder to lose.

19) Cash-only transactions (in many contexts) → Cards + mobile payments
Electronic payments are faster, trackable, and work well for online commerce.

20) Traditional “classified ads” in newspapers → Online marketplaces and social platforms
Online listings are searchable, photo-based, location-filtered, and updated continuously.
