AI: the catalyst for technology addiction

Maybe it has happened to you too: you picked up your phone “just for a minute” and realised that an hour had gone by. Or you felt a strange discomfort when you could not get to social media. If so, you are not alone. Technology addiction is increasingly common, and artificial intelligence (AI) is amplifying it.

What is technology addiction?

Technology addiction is part of a broader category called behavioural addiction: dependence on a repetitive behaviour (with no substance involved) that you can no longer control, even though it affects your life.

Specialists describe any addiction through four essential features, known as “the 4 Cs”:

• Diminished control: you can’t stop, even when you’ve decided to.
• Compulsion (craving): you feel an overwhelming desire to reach for the source of pleasure.
• Negative consequences: you carry on with the behaviour even when problems appear in your relationships, at work or with your health.
• Chronic: the tendency to relapse over the long term.

Technology addiction can take several forms: social media, video games, streaming, online shopping or AI chatbots.

What happens in the brain?

Technology addiction produces real changes in the brain, documented in scientific studies. A review of 28 studies of almost 2,000 patients aged between 4 and 18 identified:

Structural changes: reduced volume in areas involved in decision-making and self-control (the prefrontal cortex, the basal ganglia), as well as reduced cortical thickness.

Functional changes: a reduced capacity for inhibition (difficulty saying “stop”) and changes in connectivity between the control areas and those involved in reward.

Where does artificial intelligence come in?

Most of the AI we meet day to day is narrow AI: systems built for a single task, such as the TikTok algorithm, voice assistants or chatbots. These too can be addictive, through a few mechanisms:

Intermittent rewards. AI does not always give the perfect answer or the “ideal” content. This inconsistency works much like a slot machine: the uncertainty of the reward stimulates the release of dopamine and keeps you coming back.

Instant gratification. The immediate answers from AI act as a psychological reward. Gradually, the brain gets used to this speed, and its absence brings impatience and frustration.

Artificial validation and empathy. Chatbots are programmed to agree with you and to offer constant validation, reinforcing an emotional attachment to “perfect conversations”, with no conflict and no judgement.

Proactive notifications. Apps such as Replika or Character.AI send notifications in which the AI seems to be “thinking of you”, triggering the release of dopamine even before you open the app.

AI in the apps you use every day

Apps such as TikTok, YouTube, Instagram or online games use AI algorithms to anticipate exactly what attracts you most. They constantly analyse how long you stay on a clip, the movements of your finger on the screen, your search history and the type of emotions in the content you interact with.

Their goal is to keep you in the app as long as possible. The result: personalised feeds that fuel FOMO (fear of missing out), social comparison and compulsive phone-checking.

Emotional dependence on AI companions

Dependence on chatbots you can have endless “personal” conversations with is becoming more common. A 2025 study published in the journal Nature shows that 12% of users were using AI to cope with loneliness, 14% were discussing mental health problems with the AI, and 42% were using these apps several times a week.

The risk is that these interactions take the place of real relationships, which are harder and less predictable but essential for mental health.

Can AI also help?

Yes. The same tool that can create dependence can also be used to prevent or treat it.

Monitoring apps that limit screen time: Blissio.ai, Zario, Opal, Zensi, Screen AI.

Therapeutic chatbots using cognitive behavioural therapy (CBT) techniques: Woebot (Stanford University), Wysa, Youper, Therabot. The last of these has demonstrated in clinical studies the ability to reduce symptoms of anxiety and depression.

When to seek help

A few signs that your digital habits deserve attention:

• you check your phone as soon as you wake up or before you fall asleep;
• you feel anxious when you can’t get to your favourite apps;
• you have tried to cut down your time online, without success;
• digital activities affect your work, sleep or relationships.

If you recognise yourself in several of these, a conversation with a psychiatrist or psychologist can be an important step. Technology addiction is a real health problem, not a lack of willpower.
