Projections of the year 2020

Front

Humans will set foot on Mars

Back

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

Front

We'll have personal digital assistants

Back

Somewhat: Though Alexa isn't sorting through your emails (that we know of) and your smart thermostat isn't tracking your purchases, Bill 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.

Front

We'll have self-driving cars

Back

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.

Front

Books will be dead

Back

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.

Front

Computers will be invisible

Back

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.
