Obsolete technology | Replacement | Still used for |
---|---|---|
Drive-through bank teller (sometimes featuring pneumatic tubes to transfer documents and money to outer lanes) | ATM (drive-through or walk-up), online banking | Drive-through tellers still exist to serve customers who prefer not to use the available technology or to handle transactions too complex to be handled by an ATM. |

Producing light with fire. Early: candles, torches. Later: kerosene lamps, fuel-based lanterns, and gas light | Flashlights, electric lights | Torches sometimes used for performance purposes. Coleman Lanterns and similar are sometimes used for camping, but battery-powered lanterns are becoming more common. Gas lighting is still used for street lighting in some historic districts, but not indoors due to toxic emissions. Candles are still used for aesthetic purposes. Gas and fuel based lanterns as well as candles may also be used to generate light in addition to flashlights during power outages. |

Co-existence[]
Older technologies substantially co-existing with newer technologies include:
- Analog watches are still widely used for reasons of fashion and personal preference despite the availability of digital watches which can be made much lighter and with smart watch capabilities.
- CDs are still used in addition to MP3 players.
- DVDs have not been displaced by Blu-rays
- Fireplaces are still used for primary heat in some houses in developed countries, though furnaces, electric heat, and other modern HVAC systems are less polluting, can be better controlled, and can also provide cooling.
- Ferry travel has not been completely displaced by bridges and airplanes
- Fords are still used for rural roads, though bridges have replaced them for most roads in most developed countries
- Hammers have not been displaced by nail guns
- Hot water bottles continue to be used along with electric blankets and heating pads.
- Landline telephones are still used, despite the advent of mobile phones
- Long-distance travel by railroads and highway has to some degree been displaced by airplane, but not entirely - especially in countries adopting high-speed rail
- Postal mail continues to be used alongside email, but with substantial decreases in personal correspondence outside of special occasions, due to the availability of text messages and email
- Pneumatic tubes for passenger transport have been used in atmospheric railway to provide motive power, like a cable car system. Vactrain systems, where the entire passenger compartment travels through an evacuated tube, never became operational, but are still being investigated for high-speed transport.
- Shields co-exist with bulletproof vests, and are used by riot police. Lighter-weight and stronger materials are available compared to ancient wooden and bronze shields, including clear plastic shields and bulletproof shields mounted on firing platforms.
