Book summary “Obsolete”: summary

Introduction

You live in a world where familiar physical objects vanish with bewildering speed. Each new digital upgrade makes your current possessions, skills, and daily habits obsolete before you fully master them. Moore's Law accelerates this cycle, rendering mechanical devices and tangible media outdated almost overnight.

As rapid technological acceleration replaces everyday physical items with digital alternatives, society risks losing foundational knowledge, historical skills, and tactile human connections.

Anna Jane Grossman examines this cultural shift across four distinct domains in Obsolete. You will explore how vanishing technologies erode specialized repair skills and alter basic communication methods. The book then investigates the transformation of workplaces and homes through software interfaces before analyzing the erosion of privacy and physical rituals.

As you watch your physical world dissolve into screens, you must ask several urgent questions:

• What essential human skills disappear when digital automation takes over daily tasks?
• How does the loss of physical objects affect your memory and connection to history?
• What do you actually gain when convenience replaces tangible effort?

1. Defining Obsolescence and Vanishing Knowledge

Rapid technological acceleration continually shrinks computing hardware while increasing processing power. This exponential trend drives everyday items into rapid obsolescence and leaves you struggling to keep up with constant changes.

Technological acceleration continuously drives everyday items into obsolescence while simultaneously eroding foundational human knowledge and specialized historical repair skills.

Gordon Moore formulated Moore's Law in 1965. He predicted that transistor counts on chips would double every two years.

Alvin Toffler examined this psychological toll in his 1970 book Future Shock. You experience this overload when new gadgets appear constantly and erase historical skills from daily life.

The author compares her elderly friend Beatrice with modern generations. Beatrice could easily use a rotary phone and light a pilot light. Younger people rely entirely on smart devices and fast-paced digital tools.

As society advances technologically, basic foundational knowledge and specialized skills from older eras crumble away. Society mistakenly assumes knowledge is purely cumulative. You overlook the reality that foundational skills and historical repair techniques disappear as new fields receive funding.

Biologist David Ehrenfeld noted these losses in his 1993 book Beginning Again.

David Ehrenfeld highlighted specific examples of vanishing expertise:

• the scarcity of earthworm taxonomists;
• the loss of technical knowledge required to repair vintage battleship turrets like those on the USS Iowa in 1989.

Obsolescence differs from temporary out-of-style fads. An object becomes obsolete when it is permanently replaced by something perceived as faster or better.

Aesthetic trends like top hats or A-frame houses may cycle back into fashion. Items like typewriters and VCRs become obsolete because their functional purpose has been entirely supplanted.

Dedicated mechanical tools are now preserved only by enthusiasts. Richard Porter maintains a collection at the Thermometer Museum for scholars in the future year 3084 who might study antique mercury thermometers.

2. The Transformation of Communication and Media

Digital alternatives, mobile phones, and the internet have fundamentally altered how society communicates, retrieves information, and records personal history.

AM radio originally served as the dominant long-distance audio medium because its signals could travel thousands of miles at night by bouncing off the atmosphere and water. During the day, AM ground-wave signals reached only locally, but nighttime atmospheric conditions allowed strong signals to span great distances. FM radio later emerged with vastly superior stereo sound quality and a range less prone to natural interference, eventually relegating AM to sports and talk shows.

The Grand Ole Opry broadcasted country music on 650 AM WSM in Nashville starting in 1925, reaching listeners as far away as Maine and California. During the 500 to 1,600 kilohertz range for AM radio, listeners tuned in across wide frequencies. By 1962, the FCC recorded 983 commercially operated FM stations, and that number grew to 4,000 FM stations by 1975.

Arnold Neustadter invented the Rolodex to solve the mid-century domestic and corporate chaos caused by frequent changes in addresses and phone numbers. Between 1948 and 1970, an estimated 20 percent of Americans moved each year, rendering static address books obsolete. The Rolodex featured rotating wheels with removable cards, allowing you to easily update, add, or discard individual entries without rewriting whole sections. Large models could hold up to 6,000 cards.

Farrar, Straus & Giroux president Jonathan Galassi maintained five well-worn Rolodexes containing historical contacts like photographer Annie Leibovitz and poet Elizabeth Bishop.

Consumer answering machines transformed household communication in the 1980s by allowing call screening and eliminating the need to hire expensive human telephone-answering services. Before affordable home answering machines, people relied on commercial answering services staffed mostly by women to catch missed calls while you were out. More than a quarter of all US households had answering machines by 1988. When consumers adopted tape-based answering machines, call volume surged as people could manage their social obligations at odd hours without immediate interaction.

Nancy, a lifelong New Yorker, recalled getting into arguments with her boyfriend and yelling at the human operators at her answering service to let calls ring through.

The shift from landlines to mobile phones fundamentally reversed the historical power dynamic between callers and callees, liberating you from the vulnerability of unknown calls. For most of the landline era, the caller held the power because they initiated and paid for the call while the recipient scrambled to answer a device that could be anyone. A 1909 magazine ad explicitly described a telephone recipient as a prisoner of the bell. Caller ID, answering machines, and ultimately mobile phones gave recipients the ability to screen calls and talk only when convenient.

In 2007, cell phone-only homes surpassed homes with only a landline, and teenagers now overwhelmingly prefer texting to making or receiving voice calls. In that same year, 60 percent of 18- to 24-year-olds in single-person households had no home phone. Today, 13- to 17-year-olds average 1,742 text conversations per month compared to an average of 231 calls made or received.

Physical multi-volume encyclopedias served as authoritative domestic symbols of education before being displaced by online, unverified sources like Wikipedia. Door-to-door salesmen sold expensive encyclopedias as a guarantee of children's educational betterment. The physical format allowed for unexpected ambling through pages, whereas digital searches provide targeted information without the serendipitous discovery of adjacent topics.

The decline of physical dictionaries has directly contributed to a diminished ability to spell correctly in the digital era. Dictionary sales have dropped significantly since 2004, including a 50 percent drop in dictionary sales in England. Previously, the necessity of checking heavy reference books and the lack of red squiggly lines on typewriters trained generations to memorize difficult spellings. A 2008 British Spelling Society study of a thousand people found that less than half could correctly spell millennium and embarrassed.

The steady extinction of print newspapers reflects the migration of readers and advertisers to free online news and digital aggregation. Journalism professor Philip Meyer calculated that the last print newspaper will be published in the fall of 2043. As advertisers shifted to pay-per-click banners and classified sites like Craigslist, print newspapers suffered massive revenue collapses, plunging the postal service and local newsrooms into deep financial crises while daily readership among younger adults plummeted.

Only 19 percent of American adults under age 34 read daily newspapers, and 55 is the average age of a person picking up a hardcopy newspaper at a newsstand. In 1972, 70 percent of people read the paper every day, but that number dropped to 35 percent by 2000. Between 2006 and 2007, the US Postal Service saw first-class mail revenue decrease sharply, while publications like the Baltimore Examiner and Cincinnati Post shut down their print editions.

Mixtapes served as tangible, highly labored artifacts of musical affection and courtship that were ultimately rendered obsolete by easily shuffled digital playlists. Making a mixtape required recording songs sequentially from the radio, records, or CDs, forcing you to listen through the physical process and carefully curate track order, transitions, and timing. Standard cassette tapes typically lasted 60 minutes, while specialty versions stretched to 120 minutes using overly thin, breakage-prone ribbon. Unlike modern playlists or digital audio files, physical cassettes had emotional weight, physical imperfections, and permanence that made them powerful tokens of romance and personal identity.

Jason Bitner, cocreator of the magazine Found, discovered a mixtape from his 1980s middle-school girlfriend in 2007, inspiring him to launch CassetteFromMyEx.com to archive these physical musical artifacts.

3. Shifting Technologies in the Workplace and Home

Physical push-buttons are disappearing. Manufacturers replace them with touch-screens and virtual interfaces.

Modern software interfaces, digital automation, and ergonomic engineering have replaced mechanical office tools, physical processing methods, and traditional household items.

Employees at News Corporation offices on Sixth Avenue in Manhattan encountered destination lifts without any buttons inside the cars, forcing passengers to select floors on external panels or via key fobs.

Cathode ray tube monitors and televisions, which dominated living rooms and offices for half a century, were rapidly replaced by slim LCD screens. Sony announced in 2005 that it was pulling the plug on thirty-four- and thirty-six-inch tube set production at its Pittsburgh facility and closing its San Diego plant. Less than 5 percent of all media screens accounted for by LCDs in 2002. Over 95 percent of all televisions and computer monitors accounted for by LCDs by 2009.

The transition from mechanical typewriters to computers fundamentally altered the writing process. Writer Paul Auster used a battered white manual Olympia typewriter for over thirty years, praising its mechanical reliability over modern laptops. Correction fluid provided a simple physical mechanism for fixing typewriter errors before the advent of word processors. Bette Nesmith Graham sold her company in 1979 for more than $47 million.

Blackboards were for over a century the primary tool for disseminating written information to groups. The United States Military Academy at West Point in New York is thought to be one of the first schools to have used slate slabs in classrooms.

Dial-up modems used distinctive audio handshake signals to connect users to the internet over telephone lines. In 2008, the Pew Research Center reported that the population of dial-up users had been steadily dwindling since 2001.

The rise of the internet and productivity metrics largely eliminated traditional office downtime and mindless loafing. In the film Office Space, character Peter Gibbons admits to doing only about fifteen minutes of real work in a given week, an admission that paradoxically leads to his promotion. Vault.com noted that 90 percent of employees admitted to spending part of their day on non-work-related internet browsing.

Traditional executive office chairs prioritized plush appearance over ergonomic support until ergonomic engineering revolutionized workplace seating. The Aeron chair by Herman Miller was introduced in 1994 with an initial price tag of 800 dollars.

4. The Erosion of Privacy and Physical Rituals

The rise of digital exposure, automated payments, and instant media has dismantled personal privacy while eliminating tactile, unrepeatable physical rituals.

You can observe this shift in how daily routines require less touch and patience. Gum stamps relied on cornstarch-and-dextrin glue activated by saliva. The US Postal Service transitioned to self-adhesive stamps after military complaints during Desert Storm. By 1995, only 20 percent of thirty-five billion stamps were self-stick, and today roughly 1 percent of stamps make contact with a tongue.

Glass mercury thermometers were household staples for fevers. Breaking them released one gram of toxic liquid metal, enough to poison a twenty-acre lake. Seventeen tons of mercury were tossed away every year before the US Senate passed a national mercury thermometer sales ban in 2001.

Polaroid instant photography provided a tactile and unrepeatable art form. Edwin Land released the first Polaroid Model 95 camera in 1948 after his daughter asked why photographs could not be seen immediately. When Polaroid announced the cessation of film production in 2008, New York City artist Lynnette Astaire staged a full funeral procession with pallbearers and a New Orleans jazz band.

Traditional pornographic magazines required physical exertion and storage. Magazines like Hustler saw circulation drop from three million copies in the 1980s down to 700,000 in the two decades leading up to 2008 as free internet platforms grew.

Society has transitioned into what the author calls the Age of the Goldfish Bowl. A 2006 British poll of ten-year-olds voted being a celebrity as the best thing in the world, ranking God tenth.

Conclusion

As rapid technological acceleration replaces everyday physical items with digital alternatives, society risks losing foundational knowledge, historical skills, and tactile human connections.

You can navigate this shift toward digital convenience without losing your connection to the physical world. Protecting your personal memory and practical abilities requires intentional choices against total automation.

1. Preserve physical records of your life by printing photographs and writing notes on paper rather than relying solely on cloud storage.
2. Cultivate analog skills by learning how to repair physical items, cook without digital recipes, and read printed books.
3. Limit your reliance on automated convenience by occasionally performing tasks manually, such as navigating without a GPS or calculating numbers without a device.
4. Protect your privacy by evaluating which aspects of your daily life truly require digital exposure and keeping personal rituals offline.
5. Pass down tactile knowledge and physical artifacts to younger generations to ensure that foundational human experiences survive technological obsolescence.
