Analog could serve as "always-on" computing, while digital is turned on only when necessary.

Theoretical physics professor Michio Kaku outlines the evolution of computers from analog to digital and introduces quantum computers as the next frontier.

Can quantum computers do things that standard, classical computers can't? No. But if they can calculate faster, that's quantum supremacy.

Nature may not allow us full access to the weirdness of quantum mechanics.

The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer's suggestive simulation.

Computers are growing more powerful and more capable, but everything has limits

How World War II codebreaker Alan Turing invented modern AI.

The future of healthcare may bring powerful collaborations between AI and medical professionals.

Philosophy is often seen as little more than armchair speculation. This is a shame, as philosophy often has helped science reach new heights.

Science fiction movies capture a classic human flaw: getting the future mostly wrong.

Jimena Canales shares the “demons” that shaped computer science.

Perhaps wormholes will no longer be relegated to the realm of science fiction.

Brain-computer interfaces could enable people with locked-in syndrome and other conditions to "speak."

The simulation hypothesis is fun to talk about, but believing it requires an act of faith.

Flexible organic circuits might someday hook right into your head.

It will be immensely difficult for the Bitcoin and Ethereum blockchains to protect their competitive edge if they do not pursue a radical change.

A University of Oxford professor explains how conscious machines are possible.

Large language models are an impressive advance in AI, but we are far away from achieving human-level capabilities.

That scary swirling void from which nothing can escape is our perfect universal translation tool.

Elon Musk suggested remote-controlled, vibrating anal beads. Thankfully, there are more mundane explanations.

Despite their brief history, computers and AI have fundamentally changed what we see, what we know, and what we do.

Space weather poses a tremendous threat to all satellites, knocking all computer systems offline. Is that a recipe for Kessler syndrome?

Walter Pitts rose from the streets to MIT, but couldn’t escape himself.

If your computer crashes, it might be due to a star that exploded somewhere in the Universe millions of years ago.

Do humans have souls, or are we just particles? Physicist Sabine Hossenfelder explains.

The initial goal of AI was to create machines that think like humans. But that is not what happened at all.

Ada Lovelace’s skills with language, music, and needlepoint all contributed to her pioneering work in computing.

In history, every major technological advance has been used, for good and bad.

Humanity is a type 0 civilization. Here’s what types 1, 2, and 3 look like, according to physicist Michio Kaku.

Even lifelong technologists and AI researchers like myself were genuinely surprised by the speed and impact of generative AI.
