What’s all this then? Thanks to new technologies, we may soon be able to unlock the inner workings of our minds, and capitalise on our subconscious. We’re arriving at a new horizon, one that lights up the dimly-lit corners of our brains. And this will mean that cognitive liberty, ie the freedom to control our own thoughts, is set to become one of the most important topics of the next decade.

Sounds dystopian. That’s only because it is. 

Not sure if I like the sound of that. Big Tech doesn’t care. This is the final frontier for brands to stake a claim on. Did you know Apple quietly filed a patent for AirPods that monitor and track biosignals and brain activity last summer and start-up NextSense aims to sell earbuds that can collect heaps of neural data — and uncover the mysteries of grey matter for health benefits. Writing about Apple’s patent, tech expert Gautam Hazari described it as a big step in the so-called ‘Internet of Thoughts’, explaining: “The bio-sensing electrodes as on-ear EEG sensors built into the AirPods fit the generic, multipurpose device, opens the door for the IoTh to become a mainstream reality…”

But does anyone really care outside of Silicon Valley? Funny you should say that. You might have noticed that Ariana Grande’s new album and music video riffs off of the cult movie Eternal Sunshine of the Spotless Mind – a movie about memory-hacking 20 years almost to the day after it first hit cinemas. And while brain-hacking, and memory-altering tech has often been part of our creative inspiration, the key difference now is that this technology may well have caught up with our imaginations.

That’s pretty meta. So I’ll be able to erase memories of my ex? Not exactly. But we could, for example, be able to induce lucid dreams. One product in development is The Halo, an AI headband that will use a combination of ultrasound and machine learning models to allow users to control their own dreams. “Together we will pursue the answers to life’s biggest questions,” it teases. If we can hack our subconscious, we could access a whole new level of human understanding. Already the practice of using lucid dreaming as therapy is becoming more accepted, with more patients open to learning how to disrupt their dreams to process debilitating symptoms.

What’s the down side? Well, this scenario pretty much is an advertiser’s dream (pun intended). Think of all that untapped real estate in your brain. Forget DTC – we’d be going DTS (direct-to-source). In fact, A24’s recent movie Dream Scenario shows us a world where this can happen. And you can imagine how that pans out. Not to mention the implications for productivity – why rest when you can be on 24/7, conscious or not? – and our ability to exercise autonomy over our own thoughts. 

Seems like a dodgy threshold to be crossing. It’s a double-edged sword, a Faustian dilemma of the modern world: would you trade understanding – and access to a higher level of consciousness – for your own cognitive liberty? 

TL;DR: Brands and Big Tech are starting to reckon with the potential of our subconscious and our dreams in a way that might be equal parts enlightening and sinister, and we’re seeing these ideas trickle down into mainstream culture. Sweet dreams™.
