Why a 21st-century sci-fi classic packs more punch 12 years later?

Back in the mid-2010s, just before AI became something everyone and their nan pretended to understand, along came Ex Machina — a film that actually tried to poke at the edges of that tech anxiety. Written and directed by Alex Garland in his debut behind the camera, it landed in 2014 (with A24 rolling it out in America), and asked what would happen if an artificial intelligence really did become conscious – or, perhaps more unsettlingly, simply tricked us into thinking so.

The nuts and bolts are simple enough on the surface: Domhnall Gleeson plays Caleb, a clever coder from the planet’s biggest search engine, who gets handpicked to spend a week in the swish, glorified panic room that is his boss’s luxury bunker. Said boss is Nathan, one of those smug, gym-bro tech billionaires, equal parts genius and megalomaniac. The brief? Test whether Nathan’s secret AI project, Ava, actually has a mind of her own.

Released in 2014, Ex Machina remains a rare sci-fi film where the humans are often scarier than the machines.

Peeling Back the Layers

Now, 'robots go rogue’ is hardly a new pitch in sci-fi, but what sets Ex Machina apart is that it goes beyond malfunctions and menacing red eyes. There’s philosophy here: questions about consciousness, free will, and the blurring line between human and machine. It’s not really about killer cyborgs — it’s about what happens when tech bros tinker with things they really shouldn’t, and how those experiments say more about their creators than the creations.

Nathan (played by Oscar Isaac) is basically your archetypal Silicon Valley overlord dialled to eleven: gym gear, God complex, the lot. He thinks rules and oversight are for lesser mortals. The alarming bit, though, is how much his brand of ambition feels ripped from today’s headlines — all those Mark Zuckerberg and Elon Musk types who make decisions about AI in boardrooms, not parliaments, and expect the world to catch up later. Nathan isn’t just experimenting on Ava. He’s conducting a grand experiment on everyone, hoovering up reams of data from people’s phones, webcams and online searches to ‘teach’ her, all skirting any concept of consent. Garland had this nailed years before the rest of us started to worry about what our smartphones are listening for.

Ava: Real Mind or Clever Act?

This brings it all back to the big question that the film won’t settle for you: is Ava truly self-aware, or just running a wickedly effective routine to get what she wants? Garland clearly isn’t interested in easy answers, and that’s half the thrill — especially nowadays, in 2026, when we’ve all had conversations with chatbots eerily good at pretending to ‘care’ about our problems. Ava picks up on what Caleb wants, how he thinks, and mirrors it back, which is basically how every ‘smart’ device on the high street operates: they’re not feeling, they’re just learning your rhythms and habits and playing them back until you forget it’s an illusion.

If you look closer, there’s something darker going on too. Ava’s outward appearance and behaviour — attractive, soft-spoken, agreeable — are calibrated to manipulate Caleb’s expectations as a man. In other words, gendered AI is baked in: she’s made to be likeable, pitiable, almost subservient. It’s not a million miles from the way Alexa launched with only a woman’s voice, or how Siri used to sound by default. In Ex Machina, Garland weaponises those stereotypes, showing just how dangerous (and convenient) it is for a creator to build something in an ‘ideal’ (read: male fantasy) shape. Caleb’s own biases make him the perfect mark.

Moral Messiness

The film doesn’t wrap things up neatly. In the end, Ava gets help from Kyoko (another android, silent but devastatingly effective), and the pair take Nathan out of the picture. Ava locks Caleb in the bunker, then vanishes into human society, indistinguishable from anyone you might walk past on the street. There’s no evil robot uprising, just a kind of cold, ambiguous justice. She isn’t painted as a monster — at least, not obviously — nor a victim, but something in between. You’re left to wonder if she ever actually cared about Caleb, or simply exploited the only escape route Nathan’s arrogance left open.

When it first arrived, all this seemed like a smart bit of speculative fiction. These days, it feels painfully close to reality: we’re all unwitting testers in someone else’s AI experiment, with systems that adapt quicker than most of us realise and can take us for a ride without even blinking. The film’s warning feels less like sci-fi and more like a handy primer for reading the terms of service on your next digital assistant.
