WE’VE COME A LONG, LONG WAY

Walking on Mars, self-driving cars: On the way, already here or nowhere near

- Grace Hauck

Jetpacks, disintegra­tor rays, nuclear energy, Mars missions.

Decades ago, academics, futurists and government agencies cast their prediction­s of what would happen by the year 2020. Would submarines reach historic depths? Who would lead nations, and which ones would be global superpower­s? Would Planet Earth even exist as we knew it?

“I shall not be surprised if on my 92nd birthday I am able to go for a ride in an antigravit­y car,” mathematic­ian and scientist D.G. Brennan wrote in 1968.

Some, like Brennan, were overly optimistic. Others were spot-on. Here’s what happened, what didn’t and what was just plain crazy.

2. Computers will be invisible

Kurzweil had several other prophecies for the year 2019, including invisible computers.

“Computers are now largely invisible. They are embedded everywhere – in walls, tables, chairs, desks, clothing jewelry and bodies. People routinely use three-dimensiona­l displays built into their glasses or contact lenses . ... This display technology projects images directly into the human retina.”

Keyboards and cables would become rare, he said.

It’s true: Computers are embedded everywhere these days. We have smart homes, smart tables, smart chairs, smart desks and more. Though we may not project images directly into our retinas, Google Glass comes pretty close.

(Per Kurzweil’s prediction, scientists are developing smart contact lenses capable of monitoring the physiologi­cal informatio­n of the eye and tear fluid that could provide “real-time, noninvasiv­e medical diagnostic­s.” Several groups are testing smart lenses that would measure glucose levels in the tears of people with diabetes.)

3. Books will be dead

“Paper books and documents are rarely used or accessed. Most twentieth-century paper documents of interest have been scanned and are available through the wireless network,” Kurzweil predicted.

Wrong: Though the net revenue of the U.S. book publishing industry has decreased since 2014, the industry still sold 675 million print books and brought in nearly $26 billion in 2018, according to the Associatio­n of American Publishers’ annual report.

4. Your every move will be tracked

Kurzweil predicted that privacy would be a huge political and social issue and that “each individual’s practicall­y every move (will be) stored in a database somewhere.”

True, most people say: Your TV watches you. Your smartphone follows you. Your web browser traces your digital trail. In an era when some population­s worldwide live under 24/7 high-tech surveillan­ce, most U.S. adults say they do not think it is possible to go through daily life without having data collected about them by companies or the government, according to a survey of U.S. adults by Pew Research Center.

More than 80% say the potential risks they face because of data collection by companies outweigh the benefits.

5. World’s population will reach 8 billion

In 1994, the Internatio­nal Food Policy Research Institute projected the world population would increase by 2.5 billion to reach 8 billion by 2020. India, Pakistan, Bangladesh and the continent of Africa would add 1.5 billion people, the institute predicted.

Close, but no cigar: The world’s population is 7.7 billion, according to a report in June from the United Nations. The report expects the population to grow by 2 billion in the next 30 years. Around 2027, India is projected to overtake China as the world’s most populous country, the report says.

6. We’ll have self-driving cars

“Self driving cars are being experiment­ed with in the late 1990s, with implementa­tion on majors highways feasible during the first decade of the twenty-first century,” Kurzweil wrote.

Kind of: Dozens of companies – including Tesla, Google spinoff Waymo and ride-sharing giants Uber and Lyft – are testing self-driving vehicles in select locations, such as Boston, Las Vegas, Phoenix and Columbus, Ohio.

In April, Tesla CEO Elon Musk said the company would have fully self-driving cars ready by the end of the year and a “robotaxi” version – one that could ferry passengers without anyone behind the wheel – ready for the streets next year. Tesla owners can “summon” their cars, which can drive themselves from parking spots to the curb, where the owner is standing.

What about flying cars? Porsche and Boeing partnered to create “premium urban air mobility vehicles,” and Uber plans to launch a flying taxi service in 2023.

7. China will be the world’s largest economy

Speaking of China ... in a 1997 article titled “The Long Boom,” futurists Peter Schwartz and Peter Leyden said China would be on top.

“By 2020, the Chinese economy has grown to be the largest in the world. Though the U.S. economy is more technologi­cally sophistica­ted, and its population more affluent, China and the United States are basically on a par,” they said.

Close: In 2019, China still trailed the U.S. as the world’s second-largest economy, by nominal GDP.

8. It will be normal to retire at 70

In his 1994 book “The World in 2020,” British commentato­r and editor Hamish McRae foresaw retirement ages reaching 67 to 70.

“The main motive for this in Europe is cost to the state. Government­s feel that if retirement ages are not raised, the burden of paying pensions will be so high that working people will not be prepared to pay the tax levels necessary to fund them,” McRae wrote.

No: In the USA, the average retirement age in 2016 was 65 for men and 63 for women, according to the Center for Retirement Research. That number has stayed relatively steady for men over the past few decades but has increased for women.

Some European countries set 67 as retirement age, the earliest age when citizens can start withdrawin­g pensions, and several plan to raise the age in the next few years, according to the Finnish Center for Pensions.

9. Americans will vote electronic­ally from home

As the millennial generation comes of age, they’ll be able to vote electronic­ally from home, Schwartz and Leyden predicted – possibly as soon as the presidenti­al election of 2008.

Not yet: Amid fears of foreign interferen­ce in U.S. elections, lawmakers aren’t about to let you vote in next year’s presidenti­al election on your iPhone. Proponents of online voting say it could improve turnout and prevent voter suppressio­n at polling stations.

Startups are developing solutions for online voting, such as the Voatz mobile voting platform, which has used biometric/facial recognitio­n in at least four public election pilots in the United States. Last year, West Virginia began using Voatz for absentee voting for military personnel stationed overseas.

10. China will be on a path to democracy

Schwartz and Leyden predicted that, despite taking “draconian measures” to avoid an internal crisis in the first decade of the new century, China “is generally acknowledg­ed to be on a path toward more democratic politics – though not in the image of the West.”

Not really: China faces scrutiny over human rights abuses against pro-democracy protesters in Hong Kong and against nearly 1 million Uighurs, a predominan­tly Muslim population, members of which have been arbitraril­y detained and imprisoned in “reeducatio­n” camps in China’s Xinjiang region.

11. We’ll have ‘personal companions’

In his 1999 book, “Business @ the Speed of Thought,” Bill Gates predicted personal devices that “connect and sync all your devices in a smart way, whether they are at home or in the office, and allow them to exchange data.”

“The device will check your email or notificati­ons, and present the informatio­n that you need. When you go to the store, you can tell it what recipes you want to prepare, and it will generate a list of ingredient­s that you need to pick up. It will inform all the devices that you use of your purchases and schedule, allowing them to automatica­lly adjust to what you’re doing,” Gates wrote.

Hey, Alexa: Add milk to my shopping list.

Though Alexa isn’t sorting through your emails (that we know of) and your smart thermostat isn’t tracking your purchases, Gates isn’t far off. Siri, Google Assistant, Amazon Alexa and an array of smart tech in the Internet of Things readily exchange data with your other devices and respond to commands.

12. Global surface temperatur­e will increase

A report in 1995 by the Intergover­nmental Panel on Climate Change predicted that the average global surface temperatur­e could increase by about 3.6 degrees Fahrenheit by 2100.

The report predicted that sea level could increase by about 20 inches by the same year.

On track: With 80 years to go, both prediction­s appear possible. The global average temperatur­e has risen a tad more than 1 degree Fahrenheit since the mid-90s, according to NOAA. Since 1992, the global sea level has risen a total of more than 3 inches, according to NOAA.

13. Heart disease and depression will be the world’s top diseases

In 1996, the Harvard School of Public Health and the World Health Organizati­on predicted that by 2020, the world’s top two causes of the global burden of disease – a measuremen­t of the number of healthy life years lost because of sickness, disability or early death – would be ischemic (coronary) heart disease and unipolar major (clinical) depression.

Close: In 2017, the most recent year that the data set was published, the five leading causes of the global burden of disease were neonatal disorders, ischaemic heart disease, stroke, lower respirator­y infections and chronic obstructiv­e pulmonary disease.

14. Cars will be able to go months without refueling

Schwartz and Leyden predicted that by 2010, “hydrogen would be processed in refinery-like plants and loaded onto cars that can go thousands of miles – and many months – before refueling.”

By 2020, they said, almost all new cars would be hybrid vehicles, most of them using hydrogen power.

Not yet: Toyota and Honda lead the hydrogen-powered-car market, but it’s an uphill battle against competitor­s peddling battery-powered electric vehicles. In 2018, 2,300 hydrogen fuel-cell vehicles were sold in the United States – less than 1% of the number of electric cars sold, according to InsideEVs, which covers electric vehicle news.

15. Antigravit­y belts will revolution­ize warfare

Imagine a world where battles are fought a few feet above the ground as soldiers hover in midair. In 1968, mathematic­ian and scientist D.G. Brennan predicted that antigravit­y belts would “revolution­ize the tactics of land warfare,” writing that “even if the antigravit­y mechanism did not itself provide horizontal propulsion, relatively modest sources of thrust could easily be provided.”

He suspected that by 2018, humans would have antigravit­y cars and jetpacks capable of operating for 30 minutes.

No: (Unless you’re Luke Skywalker or Buzz Lightyear.)

16. Nuclear will replace natural gas

In 1968, Stanford University professor Charles Scarlott predicted that nuclear breeder reactors would make up the majority of U.S. energy production by 2018 as natural gas faded.

“Energy from water power, solar radiation, the wind, tides, or earth heat will not figure large in the totals. Power from nuclear power plants should be available in large amounts at low cost,” Scarlott wrote.

Wrong: In 2018, fossil fuels – petroleum, natural gas and coal – accounted for about 79% of total primary energy production in the United States in 2018, according to the U.S. Energy Informatio­n Administra­tion. About 12% was from renewable energy sources and about 9% was from nuclear electric power.

17. Boris Johnson would lead Brexit

In 1997, British news organizati­on The Independen­t forecast that in 2020, Boris Johnson would become a member of the Cabinet of the United Kingdom, a decision-making body composed of the prime minister and a team of handpicked members of Parliament.

At the time, Johnson, 32, was an outspoken editor and columnist but had not held public office. “Not shy in clashing with party lines, Boris would ‘renegotiat­e EU membership so Britain stands to Europe as Canada, not Texas, stands to the USA,’ ” the journalist­s wrote.

Pretty close: Have you heard of Brexit? Johnson became prime minister in July. He served in the Cabinet, starting in 2016 as foreign secretary under Theresa May. In December, Johnson led his Conservati­ve Party to victory in a national election on the promise to “get Brexit done.”

18. Americans will work 26 hours a week

In 1968, physicist Herman Kahn and futurist Anthony J. Weiner said that by 2020, Americans would work 1,370 hours a year (or 26 hours a week) instead of the 1,940 hours (37 hours a week) that was average at the time.

Unlikely: Though we work less than we did in 1968, the average American worked nearly 1,800 hours in 2018 (35 hours a week), according to the Organisati­on for Economic Cooperatio­n and Developmen­t.

19. Nationalis­m will wane

In 1968, Ithiel de Sola Pool, a political science professor at the Massachuse­tts Institute of Technology, predicted that better communicat­ion, easier translatio­n and greater understand­ing of the nature of human motivation­s would make it easier for people to connect across ethnic and national lines.

“By the year 2018 nationalis­m should be a waning force in the world,” he wrote.

The opposite is true: Fueled by backlash against immigratio­n, globalizat­ion and the political establishm­ent, populist nationalis­m was a driving force behind Brexit, the election of Donald Trump and the rise of right-wing politician­s in France, Austria, Italy, Hungary and Poland, among other countries. “Everywhere one looks, in fact, one sees nationalis­m at work in today’s world,” Stephen Walt, a professor of internatio­nal relations at Harvard University, wrote in Foreign Policy Magazine.

20. Humans will set foot on Mars

A report in 1996 by the Space Studies Board of the National Research Council said NASA would launch “possible human explorator­y missions to the moon and Mars within the next quarter century,” predicting that humans would land on Mars by 2018.

Schwartz and Leyden envisioned a similar scenario: “In 2020, humans arrive on Mars . ... The four astronauts touch down and beam their images back to the 11 billion people sharing in the moment. The expedition is a joint effort supported by virtually all nations on the planet, the culminatio­n of a decade and a half of intense focus on a common goal.”

Not quite: Though we haven’t set foot on Mars, we’ve landed eight unmanned spacecraft on the planet’s surface.
